Ask HN: What tech job would let me get away with the least real work possible?
Have you ever thought about creating your own project, which, as you say, will not be "useless". I think this is a good option. But it's up to you to decide what to do. For example, I have a dream to create something like <a href="https://audext.com/" rel="nofollow">https://audext.com/</a> but so far there is no time and money.
