For a while I was learning tube amp/vintage audio equipment repair, and at one point was about to build my tube first amp from scratch. I hadn't taken any circuits or electronics classes yet, so it was pretty DIY.
That's when I was working and going to school part time doing easy general ed classes, so I could actually do things I enjoyed. Now that I'm in school full time for mechanical engineering, all outside interests and hobbies have gone out the window entirely. It's completely sucked the soul out of me and now I'm a hollow shell of my former self, so even when I maybe get a free four hours on Sunday afternoon once a month, I'd rather just not think about anything and skate. I look forward to graduating so I can enjoy my hobbies again- that is, if I'm still capable of enjoying anything.
