Willpower? Idk

This is my first blog lol, I just joined this place and I've got no clue what to do so I'm just gonna ramble about something bugging me right now. I feel unfulfilled, like I'm not being challenged at all. Some context, I worked in air conditioning and was a boxer for a little bit. These two things made me really happy. I got beat up everyday in some way, and I looked great. I felt a sense of purpose, and accomplishment after a good day. Nowadays though, all I really do is some office chores when I work and college homework. It feels mundane and uneventful. Weirdly enough I almost miss the pain and minor injuries. Now I've got plenty of projects and things I CAN work on, but I dont feel obligated to do them because they're all optional. Like they're missing urgency. I feel like I'm wasting my time and at the same time have all the time in the world. Like a subgenre of procrastination. I'm not lazy, I get the job done when needed, but I also don't have the drive to do things that feel almost pointless to me. Like lifting weights, I love the exhaustion and challenge but picking up and putting down metal gets old to me. I'd rather do that, but in air conditioning where I constantly lift metal, but in order to get a job done and install a big machine into a house. I want to get something done but I'm not sure why it feels so bleh. Like I said, I'm not lazy (i don't think), but I dont feel urgent about anything I want to get done. Almost like life is "too easy", but then not having the skills I want or my projects done makes me feel useless. Idk, maybe I'm just complaining too much XP
