The most important here is persistence. 3D is hard on the brain, it’s very abstract and difficult at first. You got to give your brain time to rewire.
And there are levels. Once you feel comfortable doing stuff to your mesh, move on to texturing and/or animation. But don’t expect fast results. Because of high expectations and slow progress, I’ve lost many years during which I could be training. Many people did, AFAIK. Many never returned.
You got to be persistent. Try to get hooked on it, try to get addicted to it, do 3d instead of gaming or watching TV (or food, as it often happens :P) if you can manage. make it replace some task.
It takes a backhoeloads of time initially to wrap your brain around the 3d space, and that’s not even the beginning of dealing with proportions and stuff. So the most important question I would ask myself in your position would be: Will I feel comfortable in 5, 10, 20 years from now, without the skill of 3d modelling?
If the answer is no, then there you have it: here’s a wall, here’s your head, here’s a bandana. Bruteforce it. There’s no other way to start. I’ve tried several times over the past decade, and now it bugs me I didn’t make it sooner!
And yeah, there is a curve, and I hope you like snowboarding, because with a bit of persistence, it slopes down VERY fast
