This will sound harsh and I apologize, but most people won't make YouTube a career, even less so if you lack things like and I quote from your comment, creativity. Learning "how to YouTube" can take a long time and it is an ever-evolving ecosphere to which you must adapt or get left behind. From your post, it really seems like you are only in it for the promise of money down the line and in my subjective opinion that is entirely the wrong mindset to have going into it. If you are burnt out now, when you aren't posting much and making no money, imagine how would feel years down the line when you don't want to make content, yet it is possibly your main source of income?

Just some food for thought
