"The way to get startup ideas is not to try to think of startup ideas. It's to look for problems, preferably problems you have yourself.
Why do so many founders build things no one wants? Because they begin by trying to think of startup ideas. That m.o. is doubly dangerous: it doesn't merely yield few good ideas; it yields bad ideas that sound plausible enough to fool you into working on them."
Finding a problem _you have yourself_ also increases the chance that you understand the problem space.
