If you are working on something exciting that you really care about, you don’t have to be pushed. The vision pulls you.
In life it is important to be pulled by dreams and ambitions.
You do not want to be pushed by your boss or debts, you do not want to be forced to do anything. You want to be pulled by happy, encouraging, motivating thoughts.
Therefore you have to discover yourself, find out about your passions and what you love. Once you have done that, everything will fall in place. Just follow your dreams and stick to them.
In my experience no dream is too big or too extreme. Just be careful of dreaming too small, that is dangerous.
