You may not always feel that way.
At some point you may start to wonder what your legacy on this planet is. At the very least: if you've made a good use of your limited time (and the scarce resource that is your labor). (Hard mode: if you've left the planet better off than you found it?)
The last few years have pushed a lot of people's "burn out" buttons and the self-reflection of "what have I accomplished with my time?" (and "have I contributed more to good or to evil in this world?") are very easy burn out spirals to experience, so a lot of people are asking these sorts of questions now. (Including just about every day lately for months on "Ask HN", in a million different unique individual ways, if you've not yet noticed.)
You sound like you are in a very fortunate place in your life that you aren't struggling with that right now. I envy you a little. I'm also glad for you and I hope it remains that way for you.
(I've spent too much time in the last few months worried that too much of my precious labor into finished projects and net revenue generation has been spent in service to the greater evil than the greater good of the world and have been struggling to figure out what that means or what I do with that cursed feeling.)
