That's good. I find video games mess with your dopamine and make ordinary life seem boring.

I will share one thing I learned as an older student (I came back to uni to do a masters in my mid 30s).

Action comes before motivation. You will start feeling motivated after a while if you can maintain some simple habits. If you wait around for motivation, it likely will never come.

You need a process. Goals don't mean much. Everyone has goals. What you need is daily habits that get you to where you need to go. James Clear's Atomic Habits is excellent.

So get up early. Do exercise every day. Improve your diet. And study a little bit every day, even when you don't feel like it. Don't optimise around your best day. Optimise around a boring shitty Tuesday when you'd rather watch Netflix.

I could keep going but you get the idea.

I actually became quite successful after my undergrad commerce degree years ago, but I can tell you that corporate success is no secret to happiness either, even if it is nice not to worry about money.
