Ask HN: What can I do to better stimulate my mind for business ideas?
5 by _davebennett | 4 comments on Hacker News.
I often read advice saying that you can't just sit down with a piece of paper and start coming up with business ideas; it just doesn't work that way. Many people seem to suggest to just start naturally doing stuff and "notice" the problems that you encounter. Paul Graham and Peter Levels both seem to advocate for this approach. My problem is that I rarely get any ideas I notice. Maybe I'm not doing enough stuff? Maybe all my stuff is very basic? Is there something else that I could do everyday that will "exercise my mind" for coming up with business ideas?
