Three months ago, https://news.ycombinator.com/item?id=8187802 you wrote that you are 35 years old, have recently switched jobs, and "feeling like I'm home."
35 is not a mid-life crisis.
One of your HN questions is "Sorcerer, mage, wizard, magician, what's the difference?" You also asked it at http://rpg.stackexchange.com/questions/50672/sorcerer-mage-w... .
That has nothing to do with an alignment of anything.
According to your questions, you are working on a lot of things, from C64 to BDD and Kanban, from genetic algorithms to photo backups, etc. For examples, "I bucket-listed a simple game dev project for myself and looking for inspiration", "Genetic Algorithms side project? As a hobby, what would you build?".
Don't think you need to be inspired. That's a great way to failure. Just start doing it. Don't worry if it's not good enough for anyone else to see, or even care about.
If you are in a depressed state, and unsure about what to do in life, you are not alone. My experience is that many people are that way. The best approach I know of is to talk with people, in real life, about it, or to start doing things you want to do without worrying about long-term goals. There is also professional advice for these matters - which can surely provide more helpful feedback than replies from HN strangers like me.
