Apologies if this veered too much off topic. I've been kicking this around for a week or two, and felt the need to add recent events and post.
It's 5am, I haven't eaten in 12 hours, had anything substantial to drink in about 8, have been sitting on the toilet for over an hour, and instead of doing something about any of those things I'm editing a comment to fix a typo.
I know it's a grating saying, but the journey of a thousand miles begins with a single step. It's true.
You don't have to succeed, you don't have to enjoy it, it won't be easy, but you do have to keep trying. Try to do whatever single action you can get yourself to do in the given moment that gets you closer to your goal. Then do it again. And again. Again. Etc etc etc. You'll at least be closer, and that's something.
