From inspiration springs enthusiasm. Enthusiasm is one’s attitude of confidence, curiosity and expectation, with fragments of daring and risk.
It is a very strong force that brings vigor to one’s day and draws people. Note that pessimism, negativity, anxiety and apprehension drain the energy within you. So focus only on the positive side in every situation that you encounter; this way, things get done more easily.
So to sustain motivation, it requires rationalization that is anchored on positive outcome from endeavors.
