Think of a project that is interesting to you first, the next step is how to make it profitable. People will love everything that is done with a pure heart, when this is done with love.
Yeah, agreed. Try to find out what is interesting for you and what you can do with passion and love. Do a market research and see what is needed in your region.
And to generate new ideas you should keep your mind open and do some of the following:
travel, meet new people, discover some places, cultures, find new hobbies....
Get luck!
