How do you stay productive and stop procastinationi?

A bit of background - I'm a 17 year old, currently in high school. Let's just say, I'm not a productivity machine.

I've tried everything out there - Ali abdaal, notion, etc...but none seem to work.

Cl, they make me procastinate more and plan less effectively. It doesn't actually make me do it.

How do you guys just get on with your work?

Edit: I'm making this tool called Do It (although you need to search doitszn on the web) that helps solve these problems. Lmk what you guys think!
