A character is our natural temperament modified by factors like childhood training and environment, our thoughts and feelings from specific experiences gathered in life, or a more generalized consensus of life. Your character is not something that is stagnant and unchangeable; it is something that is shaped by the way you choose to respond to everything that happens to you throughout your life. You get to choose to strengthen or weaken your character by how you choose to respond to everything in your environment.
Pragmatically there are only two choices you can make: you choose to be a “winner” or you choose to be a “whiner”. “Winners” are positive, believe in the potential and are in an empowered state eager for success. “Whiners” are negative, always looking for someone else to blame, they have no self confidence and are completely dis-empowered.
