How do yall afford living alone?

I’ve lived with roommates for most of my adult life and am ready to have my own place where nobody will disturb my peace. I dream of my solitude and nobody’s passive aggressive personality every other day. lol

But how are yall doing it? I live in ca and make a good living (90k a year) but unsure how to financially afford an apartment that costs 2300-2800 while also paying my car, insurance, cell phone plan, gym Etc etc

Would love to hear your thoughts and tips on how you’re making it work.
