People say "never give up" but sometimes giving up is the best option because you realize you're wasting your time meaning. If you analyze the situation and you realize that you are never going to reach your goal then continuing to try and fail over and over again is a waste of your valuable time and energy. This time and energy is better directed in another way instead. If you love someone who does not love you back then you can not force them to change how they feel, no matter how long you try or what you do. In this situation it is better to realize that it Is hopeless to continue trying and to give up on this dream no matter how much you might want to achieve it. If something is a waste of time then it is useless to keep pursuing the goal, it is better to give up and move forward instead of being stuck in the same cycle.
