You can do whatever you want to do, only if you make your mind to believe in this things! if you can believe that you can do some particular thing, how difficult is it in the eyes of the world, you could do it, and then the world will appreciate you!
We are known for our company around us, we learn from our company, if we are keeping good company, we will learn the good thing, and if our company is bad, it will put bad impact on us.

It is very rare that you keep a bad company and you do work opposite!
