Courage is the ability to resist provocations and remain calm in any situation. Fear, anger, resentment, anger look for any reason to break free, but a man of courage is smart, and knows that you do not need to react to lies and deceptive maneuvers.
Do not give in to provocations, you need to love yourself. To love yourself means to protect your health and not allow yourself to be afraid. Fear is very bad for everything. Don't believe in fear, just don't believe. Especially do not sublimate it into anger, aggression, laziness, sadness and apathy.
A cunning subconscious mind can rigidly substitute a dependent, cowardly or lazy person who for some reason does not want to work and realize their dreams. The body can get sick to give the mind an excuse that it is not able to implement its ideas. This vile lie must be stopped at the root and ignored.
