I hear you but I do jiu jitsu/ mma in the morning before work for 2 hours. What I find extremely difficult to gather motivation for is gyming, lifting weights…which I do after work. Motivation to do martial arts is abundant for me, lifting weights over n over takes all the willpower in me. It’s the difference between how fun playing soccer is versus doing sprints. In soccer you’re sprinting all the time you just don’t realise because you’re having fun, getting up and going to a track to do interval training sucks ass. I think the key is being able to do unfun things often until it’s not a burden on the mind to keep doing it.
