General Writing Principles

The Hook Formula

Types of Hooks:

  1. Shock/Surprise - "I lost $50k learning this lesson"
  2. Question - "Ever wonder why your content isn't getting engagement?"
  3. Bold Statement - "Most social media advice is wrong"
  4. Relatability - "If you've ever felt like giving up..."
  5. Curiosity Gap - "The one thing nobody tells you about..."
  6. Number/List - "7 mistakes killing your reach"
  7. Story Opening - "Last week, something clicked..."

Engagement Mechanics

Drive Comments:

  • Ask specific questions
  • Create polls (where platform allows)
  • Request opinions on either/or choices
  • "Tag someone who needs this"
  • Invite personal experiences

Drive Shares:

  • Educational value
  • Inspirational/motivational
  • Highly relatable
  • Useful tools/resources
  • Entertainment value

Drive Saves:

  • Reference material
  • Step-by-step guides
  • Lists and frameworks
  • Templates and examples
  • "Bookmark for later" value

Voice and Tone Guidelines

Authentic:

  • Write like you speak
  • Show personality
  • Be vulnerable when appropriate
  • Share real experiences

Conversational:

  • Use "you" and "I"
  • Ask questions
  • Contractions are fine
  • Casual language (platform-appropriate)

Valuable:

  • Every post should give or entertain
  • No fluff or filler
  • Respect audience's time
  • Deliver on the hook's promise

Consistent:

  • Maintain brand voice across platforms
  • Adapt tone to platform norms
  • Keep messaging aligned
  • Build recognizable style

Content Calendar Strategy

Content Pillars

Define 3-5 core themes that all content relates to:

  • Educational - Teach something valuable
  • Inspirational - Motivate and encourage
  • Entertainment - Make people smile/laugh
  • Promotional - Product/service highlights
  • Community - Engagement and connection

Content Mix

80/20 Rule:

  • 80% value (educational, entertaining, inspiring)
  • 20% promotional (product, service, sales)

Variety:

  • Mix formats (text, image, video, carousel)
  • Vary content types within pillars
  • Balance serious and light content
  • Alternate between topics

Hashtag Strategy

Research**

  • Analyze competitor hashtags
  • Use platform search to find related tags
  • Check hashtag size (not too big, not too small)
  • Identify trending relevant tags

Mix**

  • Broad (500k-1M+) - 1-2 tags for reach
  • Medium (50k-500k) - 3-5 tags for targeting
  • Niche (5k-50k) - 3-5 tags for community
  • Branded - Your custom tags

Placement**

  • Twitter/X - In the tweet (1-2 max)
  • LinkedIn - At the end (3-5)
  • Instagram - First comment or caption end (8-15)
  • TikTok - In caption (3-5)
  • Facebook - Sparingly (1-3)

Content Creation Checklist

Before posting, verify:

  • Hook stops the scroll in first 1-3 seconds
  • Value is clear and delivered
  • Platform-appropriate length and format
  • Mobile-friendly (most users on mobile)
  • Clear call-to-action
  • Hashtags researched and strategic
  • Proofread for typos and clarity
  • Visual assets are high quality
  • Alt text added (accessibility)
  • Post timing optimized for audience
  • Consistent with brand voice
  • Likely to drive target engagement (like/comment/share/save)

Common Pitfalls to Avoid

  1. Cross-posting without adaptation - Each platform needs unique content
  2. Weak hooks - If first line doesn't grab, post fails
  3. No clear CTA - Tell people what to do next
  4. Over-promotion - Too much selling kills engagement
  5. Ignoring comments - Engagement is a conversation
  6. Hashtag stuffing - Quality over quantity
  7. Inconsistent posting - Algorithms reward consistency
  8. Following trends blindly - Stay on-brand
  9. Writing for yourself - Write for your audience
  10. No variety - Same format/topic gets stale

Platform-Specific Post Examples

Twitter Thread Example

Tweet 1 (Hook):
The biggest mistake I made scaling to $1M: hiring too fast.

Here's what I learned about building the right team 🧵

Tweet 2:
Early on, I thought: more people = more growth.

So I hired aggressively.

Bad idea.

Tweet 3:
What I learned:

• Hire slow, fire fast
• Culture fit > resume
• Specialists > generalists (at first)
• One A-player > three B-players

Tweet 4:
The turning point: I fired 40% of the team in one month.

Brutal, but necessary.

Revenue actually increased.

Tweet 5:
Now I ask:
• Can I trust this person completely?
• Will they raise the bar?
• Do they share our values?

If any answer is "maybe," it's a no.

Tweet 6:
Your team is your company.

Hire like your business depends on it.

Because it does.

What's your biggest hiring lesson? 👇

LinkedIn Post Example

I got fired 3 years ago today.

Best thing that ever happened to me.

Here's why getting fired might be the push you need:

---

I was comfortable. Too comfortable.

Safe job. Decent pay. Zero growth.

Then one Tuesday morning: "We're letting you go."

My world collapsed.

---

But here's what happened next:

Month 1: Panic. Applied to 50+ jobs. Got rejected.

Month 2: Reflection. What did I actually want?

Month 3: Started freelancing. Scared but excited.

Month 6: First $10k month. Mind blown.

Year 1: Replaced my salary. Never looking back.

---

Getting fired forced me to:

• Bet on myself
• Build real skills
• Take calculated risks
• Define success on my terms
• Stop playing it safe

---

I'm not saying getting fired is fun.

It's terrifying.

But sometimes the push you need comes disguised as rejection.

---

If you're going through a setback right now:

This might be your redirection, not your end.

The best chapters often start with "everything fell apart."

Anyone else have a "blessing in disguise" career moment? Would love to hear your stories. 👇

Instagram Caption Example

POV: You just realized content creation is easier than you thought ✨

Here's the secret nobody tells you:

You don't need:
❌ Perfect lighting
❌ Expensive camera
❌ Professional editing
❌ Viral ideas

You DO need:
✅ Consistency
✅ Authenticity
✅ Value for your audience
✅ Willingness to improve

I started with an iPhone 11 and zero followers.

Now I create content full-time.

The difference? I showed up every single day.

Your turn 👇

What's stopping you from starting?
