That said, I have decided more and more in my adult life that I am not going to struggle needlessly. If doing so only affected me, fine. But when I have a shitty day(s) at work because I didn't get anything done, my wife gets to hear about it. My family gets to experience me being less jolly. Etc.
My focus these days is on being the best person not only to myself but to those around me. That means if I need to take some stupid pill to enable robot-mode then that's what I need to do.
I've tried the "don't let your work output be your identity" approach. That ship sailed in elementary school man. Success & output are weaved into your psyche from a very young age. To truly divorce myself from that burden I would need to completely change my life and go live in a commune somewhere. Not realistic.
And for the record, I actually really don't like the feeling of being on medication. It turns me into a robot with slow reaction time. Great for reading a book or focussing on some boring work... But horrible for the things I love in life which are all fast-paced sports and video games. If I can avoid medication, I absolutely will.
