Ask HN: How do you execute and apply yourself better?

There are a few things in life I would like to grow and achieve, i'd like to build a better life for myself and i have some goals around that, which seem like intreasting and possibly exciting oppurtunties for me.

At the start of the year I identified the biggest problem I had last year was in execution and applying myself, basically I need to be able to focus, do things at a faster rate and just get done what I know I need to.

I decide to go 'all in' this year. But when it comes to it, i'm tired, my mind wonders, I get overwhelmed about what to do, there are too many intreasting things all over the place and while I get things done, my progress is too slow to really achieve what I would like.

But I cannot really make sense of it, I fear that i'm just going to keep going at this current pace and therefore end up like I did last year with not really making good progress.

Any tips for going all in on your goals? How to apply and execute better if your someone not so good at that?
