How can I Hyperfocus?

Genuine Question,

How,when I try to focus even on things I like I get distracted by my thoughts (a bit like data overwrite).

Even If I try to focus on my Hobby's it just doesn't hold up,this especially gets on my nerves when I try to sodor something but no then it's just the current financial recession or other things that cross my mind.

Any ideas how I can concentrate for more than like an hour? I am literally not even AuDHS
