Mistake 1: Treating Claude Like a Search Engine
Claude isn't for finding information.
It's for reasoning about information.
Wrong use: "What's the best cold email tool?"
Right use: "Here's my use case: [details]. I'm deciding between Instantly and SmartLead. Compare them across deliverability, ease of setup, cost at 50K sends/month, and integration with Apollo. Factor in that I value support quality highly. Give me a decision framework."
You get analysis, not just facts.
Mistake 2: Not Uploading Source Material
"Analyze my campaign performance."
But you don't upload the CSV.
Claude can't analyze what it can't see.
The fix: Always upload the actual files. CSV, PDF, screenshots, whatever.
Vague descriptions → vague analysis.
Actual data → specific insights.
Mistake 3: Accepting First Drafts
The difference between good and world-class is iteration.
First draft: 6/10
Second iteration: 8/10
Third iteration: 9/10
But most people stop at 6/10 because it's "good enough."
Your competitors who iterate are publishing 9/10 content.
Guess who wins?
Mistake 4: Not Using Projects
Every conversation starts from zero context.
You repeat yourself constantly.
Your instructions don't persist.
The fix: Create Projects. Upload docs once. Set instructions once. Every conversation inherits that context.
Context persistence is everything.
Mistake 5: Forgetting Claude Creates Actual Files
"Write me a report" → You get text, you copy-paste into Google Docs
"Create a .docx report" → You get a downloadable Word doc
One extra word ("Create a") gets you a finished deliverable instead of raw text.
