One important key to success is self-confidence. An important key to self-confidence is preparation.
And preparation doesn’t come from cramming.
Preparation comes from a daily build up of skills acquired through daily practice. Preparation comes from a constant reassessing of oneself to make oneself better. Preparation comes from uncertainty in oneself faced every single moment of every single day for so long a time that it becomes the norm.
Self-confidence comes from preparation, and preparation comes from facing doubt. Your level of confidence speaks measures about the levels of unsureness you’ve survived.
Be unsure. And get over it. And repeat.
