To make more money, you must work hard for it and also take the risk while you are young. If you fail then at least you tried and experienced it, aftewards learn from that failure. From there, you'll gain confidence in what you are doing because you know already and understand how it should work.
Making more money is not a big deal and that too in the very present moment when you are having this much of opportunities of making a very good amount of money. The only thing which matters the most is your own motivation.
If you actually want to make more money, then you really have to burn your midnight oil. You can achieve everything you do want to achieve but you have to work for it.
