What are the two worst habits of thinking startup ideas?

The two worst habits of thinking are (1) sitting and thinking and (2) thinking by logic guess and local deduction. Let me explain why they don't work.

First, startup a business has something to do with business. Business is conducted in a market, in the channel, in the factory. The big problems that need to be solved are all manifested there. The best way to think is to observe, is to have first hand experience.

There are too many ideas. Leave your chair, and ideas will start to rush to you.

Why logic doesn't work? that is because logic is based on deduction of facts. However, when someone insists on "logic thinking", that person knows a lot of book knowledge but not much facts. Facts about the market, the factory, the people and the customer are all missing. Without such critical facts, any logic thinking is just "academic" - deduction based on a small limited data set.

When you start a business, you want to do good. But you must know all the stake holders and satisfy everyone to make that happen. If you want to do good, you have to defeat the bad - and you only defeat the bad when you have allies on your back.

Don't think logically. Logical thinking should be done in the market observing "illogical" behaviors. That is the only way to come up with good ideas.
