Unless you just have no interest in expressing yourself and/or create things fur yourself and others to enjoy, it's a discipline issue. You have to find a way to get yourself to draw regularly in order to progress past the toddler phase after which it hopefully becomes more fun and rewarding. It's the same as with other creative hobbies like playing guitar.
If that still interests you, just make a habit of drawing every single day. Make it a routine just like brushing your teeth (>implying). Even if you don't feel like doing anything creative, just do some scribbles, circles and crosses just so that you don't lose the streak. When you have the time and energy, do exercises or at least some fun doodles.
If maintaining discipline on your own is an issue, a study group would help (not that I've tried but it works with schools and universities).

It's fairly popular and well-known, and fur a reason, even if some folks shit on it. It offers a very logical approach, since everything can be broken down into basic shapes, you just have to be able to transpose these 3d shapes onto a 2d canvas first, and then create complex shapes out of said basics. You're going to have to develop spatial reasoning skills sooner or later either way. Doing the exercises slowly rewires your brain so that eventually you can draw these simple shapes at any angle without thinking about it too much.
It doesn't just discuss objects in 3d but also covers textures, shading etc.
The drawbacks are that it's dull and grindy (and you should complement it with something more fun) and the author seems to be autistic. Even the website layout is not really user-friendly.
Some more chill books I've seen recommended are those by Loomis (Fun with a Pencil literally starts with silly face doodles), Figure Drawing by M.Hampton. Keys to Drawing, Drawing on the Right Side of Brain fur more generalized stuff.
