So, you want to make money with photography? One thing you have to understand is that you are going to hear a lot of criticism on your work before you get to the level of pro. And you will have to accept it and not take it so personal.
How and why would you do that? You steel yourself for the criticism and revel in the praise. You need the criticism in order to know what areas you need to improve on. If they tell you your picture isn't crisp enough, sharp enough, or your highlights are blown....whatever it is, you read up on that and you apply what you learned to future photographs.
That is how you take photos that are good enough for someone to be willing to pay you for it. If you want it bad enough, you keep going and never give up. Do that and you will succeed.
