My secret was to play for 20 minutes in the morning when I first got up, 20 at night before going to bed, and 20 minutes somewhere during the day. That gives you 60 minutes a day.
You're really only focused for about 20 minutes anyway, so after that youre basically wasting your time anyway. Better to get three focused sessions per day, than one long one where you weren't really concentrating for most of it. And if you miss a short session, you only miss a little, you don't skip an entire day.
Force yourself to do that for 2-3 weeks, and it will become a positive habit that will feel weird if you skip it. Hopefully, you are so motivated to go on your musical journey that you won't need to convince yourself too much, but it also helps that your progress will be so fast that it will become self-motivating.
Eventually, I got away from that schedule, because I was playing a lot more than that per day anyway. I've became a bit obsessed.
3 x 20 min per day. That's what I did, and I was shocked at how quickly I progressed.
I get it, it seems pretty obvious, but MAGA has spent years convincing many people that only good can happen, and a lot of them still buy it.
