Noticing frustrating bits and lack of better options is a habit, I believe, which has to be developed. It&#x27;s easier to notice horribly frustrating things and that&#x27;s what startups often do, but that might be out of scope for many side projects. However, noticing small things that might be fixed in an evening or a week - that&#x27;s a habit. I find it similar to the &#x27;I want to blog, don&#x27;t know what to write&#x27; issue.
