Story of time 

It is enough to do one thing well in a lifetime, before you do not choose to do this thing, to constantly try and make mistakes, try a lot of things.
But every thing of trial time can not be long, a few months is enough, even if you just pay the tuition for a few days, find that this thing is not suitable for you, then also have to give up it, do not have to kill time. Try enough things, you will find which thing is what you are best at, at the same time like, people can not like many things, there must be a relative, the most like, and the most good at.

As long as you are good at it and like it, you will settle down on it, practice it, optimize it, and make it better, so you will like it more, because things are done very well, you are always getting positive feedback, such as making a lot of money, getting recognition from others and so on.
You can’t want to do a lot of things at the same time, what you are good at and what you like, you can only find one of them, try not to do the rest, and you do only one thing well for many years.
