I know of someone who has learnt a lot of skills too and he didn't master any of the skills and till date his not using anyone to make money, people should stop being in a hurry to make money calm down and learn a skill and it should be a skill you love with passion after learning it go into it focus your attention into it when you are now a master in that skill you will start making huge amount of money.
I'm not saying learning different skill is not good but master one before going into another.
There is no one who can master everything if he is learning everything together. Take the example of women at home, they know how to clean the house and how to cook and how to rise children, however if you suggest one of them to start a business with one of those skills providing services for the market, they will fail as fast as possible. The reason is that mastering a skill isn't enough to get money income from it because you have to master how to run a business (business management) and how to not confuse with the main job if you make the business your secondary source of income.
