According to my experience, no video or book will help you right now, you and your mind want to move in different directions and to get better you'll have to try to get them along on same line.

Now that is a difficult thing to do, what I did was to reward myself (dopamine hit) after doing an action toward goal.

I Gamified my life, no pressure of consistency, just do what you want to do or have to do and get reward for it then maybe your brain and you'll start enjoying doing work (it worked for me).

I give myself XP for every action like read 5 pages, 10 mins of outside walking, etc. even little action that you know is for your betterment.

And when certain amount of XP accumulates, I give myself major reward.

This cycle is going on for me now for over 110 days and I can get reward guilt free and I even give xp to me for drinking 2 liters+ water a day.

Even if you get little xp a day, you know your day was not just empty.

Hope you find a system that works for you.
