How to actually start accomplishing things?

Hi guys, and dudettes.
I stopped gaming to make my life better, this weekend im selling my PC.
I have lots of things to do- like getting into university, getting better job etc..
How to actually do something productive after full time job?
Like its winter soon, so less sunlight and desire to live. Also I have pretty stressful life.
How to start studiyng at the evening instead of unwinding on youtube ot scrolling?
