How to Pick a Business Idea Without Being Delusional

[kherbo]

The internet sells fantasy business ideas. Real business is simple:

• find a painful problem
• sell a clear solution
• deliver consistently
• repeat

My filter for business ideas:

1. people are already paying for it
2. the customer can be reached easily
3. you can deliver it with your current skills
4. it can scale with systems

Question: If you had to start from zero, what business would you start and why?
