I want to quit so badly. Please tell me it is a good idea

I'm fantasizing about quitting on the spot every day and I think coming Monday I'm going to do it. Actually I don't have anything lined up but I hate it there and I would rather continue freelancing instead of this sh*tty boring job. I can't stand working full time and I think I will never be able to do it no matter how hard I try. Please give me some courage. I need to know I'm doing the right thing 🙂
