One thing which will always help you in your life is the knowledge. Try to gain as much as knowledge possible and than develop the skills which will make you the best in that field of your interest. Than nothing can stop you. Diversify the skills as and when require so that you are always up the mark in this fats world.
What do you mean by fat world. 
Knowledge alone wont make you the money,you must have the determination and money to invest in the first place and have the sense to make bold decisions whenever needed and that is how you make money in this world,i prefer to stick to one skill rather than diversifying,as life is all about fun and not to make money all the time
