Depends on the week, there are weeks where I can squeeze only 3h, and then there are weeks when I can squeeze 15h (very rare).
What has worked for me is and tips:
1. Keeping a planner - it helps me manage my time better
- Forest (any other tracking method you have) - so I actually track my time, so I can see how much time I spend on drawing/studying/more and I can plan my life better with this info.
3.the 10 minutes rule. No matter how busy I am, I need to find 10 minutes to draw and make an actual progress.
I am student (yes, I know you didn't ask for my opinion but I answered anyways so :p)
But still it doesn't mean I actually have more time than you or anyone else. I have school and an outside learning activity so my schedule is:
I get home only at 9pm 2 days a week, every other day I get home at 4pm, and at Saturday I don't have school. Now, I need to dedicate about 15 hours a week to studying in my free time each week(I tracked it, and this is the average for me), trying to exercise everyday for an hour, getting 8hours of sleep and babysitting my little cousin (2 y/o) so yep, I don't have that much of a free time lol. (Plus with me meeting with friends/going to the doctor, zero time).
