A relaxed mind
Being relaxed always is most under rated yet it is the biggest thing that can make difference. A relaxed mind is the best state of mind and most productive. 24 hours of being relaxed is more productive than a month of zigzag and stressed one. That’s the most important thing which makes difference between being super smart and dumb. Being relaxed does not mean you don’t have to be hustler, industrious or ambitious.
Its an art to achieve things while being most relaxed. And that is also a great way to achieve things. A relaxed mind is capable of taking best decisions.
There is an interesting story where a guy wants to climb Mt. Everest.. While starting he is very calm, relaxed and determined for his goal. This is his best state of mind and any decision taken at this time is best decision he can take. However, upon climbing almost half of Mt. Everest, he is stressed and tired. He has stopped enjoying the climbing as stress has come in his way. He had not trained himself to be relaxed and even worse, does not understand the importance of calmness. He reaches a flat area. He starts brainwashing his mind that with such a good view already, whats the point of climbing more? This brainwashing and stress made him never achieve what his calm mind would have. He is forever in misery now till he is relaxed again as he had taken decision with a stressed and tired mind.
