For flurry dissipates energy, and worry constipates it.
It is natural that people feel worried and scared no matter how old they get, no matter how much experience they have, no matter how much they learn and get educated. It doesn’t matter how tough and strong they show themselves because the truth will eventually reveal itself.
If you fail to recognize the real problem which hidden inside of yourselves will eventually cost a lot than throwing a cheap layer of pride on you and become honest yourself to overcome the problem one by one. Otherwise, you would find yourself complaining, telling people your excuses not to do what successful people do.
Stand up, take a breath and just do it!!
