There are internal obstacles. In order to achieve anything we have to practice. The rule of thumb says we have to spend 10 000
hours of practice before we can master anything. Even if we are talented we have to practice this much.We have this time, but all of us do not use it in a systematic way. But those who do become good, in whatever it is like music, computers, writing, sports, business.
Our most important organ to practice is mind, independently of what we are interested in concretely. Music is mind, computers is mind, writing is mind, sports is mind and business is mind.
Then we have external obstacles. There are many of them. The expectations of others are often limiting. Competition creates limits. Habits creates limits. To follow a norm might be difficult enough, as many norms are so extremely demanding, but to break a norm is even more difficult.
However, social norms and individual norms are not absolute. Even if it seems so sometimes.
There is one way to dissolve this social oppression. It is simple to state: Everyone decides not to thwart the good ambitions of others.
