What should you do for a career????????
Do what you are great at. Everyone was born with a talent. This is what you should pursue with all of your energy. Do not worry about whether you will make money from it. You will make money from a talent if you are very good at it. The people who suffer are the people that are mediocre. You will make money if you are truly one of the best at what you do. This holds true even if what you do is not particularly marketable. Be great at something and the market will open for you.
