If you give up on all your plans now, you are giving up on that part of your personality which wants to be happy. If you deny it that happiness, you are denying yourself the satisfaction you would feel after having achieved it. Giving up sets you back a step and it makes your path more difficult. It scatters it with hurdles, not ones which make you grow, but ones you trip up on, and only then learn something from: You learn you should never have given up.
Today is the day to throw your decision to give up to the wind and to watch it disperse and disappear. Step into this day with your head held high because your path is clear.
