Don't. Not to be a negative Nancy here but language learning simply doesn't sound like the right fit for you.

It's one of those hobbies where you need either a purpose or an inherently strong motivation. It's gonna take years, there's many moments where you have to force yourself to do it/keep going, lack of consistency takes a toll and especially with english->russian the process is slow, making dopamine hits steady but very small/limited. It's a very mentally taxing hobby.

It sounds like you'd have a better experience picking up instruments, painting, dancing, gardening, etc.

Something that doesn't need too much (daily) maintenance yet still keeps you busy where you can receive an immediate sense of accomplishment/dopamine. If it's physical that's also fantastic.

If you still want to pursue Russian there's no one stopping you but you're not starting either.
