The mind can only focus in one direction

Aiming in different directions at the same time will just make the target more difficult. The mind is built to direct attention with incredible energy, attention and precision to an action. If one directs the attention of his mind to many things at once, he creates a false belief that he is more productive when in fact all he succeeds in doing is disorganizing his thinking by directing it to different things and leading to a serial occupation-learning without ideal development.

Focus on one thing, dedicate yourself to it and master it before moving on to the next!
