When you do not know acknowledge it, try to learn; when you do know never hesitate to express yourself. The world is a funny place, where naysayers will demoralize, ignore, or even ridicule you. Probably, the fact that you know will irritate a lot of people and even be criticised for it. In a lopsided world, it is a brave step to hold on to the confidence and have clarity to dispel the damning attitude. Every day is your opportunity to learn and mature to remain focused on the journey you have chosen.
