How to come up with a startup idea [Tech & Non Tech]

There are lots of wannabe entrepreneurs who are stuck because they can't find a good idea to get started. Typically, here's a process of finding a good idea that you can really work on -

1. Find a problem:
Find out what problems you face in day to day life.

2. How many people are affected:
Be sure that if you are facing a problem, others are likely to have faced the problem.

3. What would you do to permanently solve the problem for yourself:
There can be two ways to solve the problem you face - temporary & permanent. The permanent solution to your problem can lead to an idea of a product or a service.

4. Implementing the idea:
Think about how can you go about implementing that idea. Do you have the right technical know-how to work on that solution?

5. Think big:
Then think how many people can benefit from that idea, if executed well.

6. Revenue: Don't even bother about this until you have a working model/prototype of your idea. If your idea solves a problem for a large number of people [your colony, town, city, country, world etc.] money will follow.
