the way to get startup ideas is not to try to think of startup ideas.
.. Real problems are interesting, and I am self-indulgent in the sense that I always want to work on interesting things, even if no one else cares about them (in fact, especially if no one else cares about them), and find it very hard to make myself work on boring things, even if they’re supposed to be important.
My life is full of case after case where I worked on something just because it seemed interesting, and it turned out later to be useful in some worldly way.
