Jesus you got a lot on there. But a lot are very reasonable. A few of my initial thoughts if you don't mind:
- Be careful of owning a gun. I've always wanted one myself, but statistically, if you're prone to depression, you may just end up shooting yourself in the head with one. I've had enough dark thoughts in my life I don't think owning one is a good idea for me, so I haven't.
- As I mentioned in the other thread, instead of jelqing, try a penis extender. They have good evidence showing they work, and by applying gentle traction over time, you are less likely to injure yourself. You would ideally want to shop for a sleeve based system like
this one, though I can't vouch for that exact model.
- 4 languages will require a lot of brain space unless you are gifted with languages. I'd be sure you're really going to need/use them before you put all that time/effort in, especially if you're in your 40s at this stage.
Otherwise, I'd say start with the easy and more attainable stuff (eg. dance class - why the f*** not start now?) and then work up from there. It's a nice list, and it tells me from its diversity and mixed practicality and whimsy that you still have joy and hope in your life, which is certainly a good thing. Most of us could use more of that.
