When you give up, you quit. You quit on yourself, and most importantly, you quit on trying. Contrary to what you think, you ain't going to find the real exit just by quitting..if it was that easy, everyone would've quit.
What is quitting? Quitting is giving in to your comforts, quitting is giving in to your laziness, your attachments, and most importantly, giving up on respect, integrity and will. Why do we quit, and choose the easy way out? Because it is easier than pushing ourselves. In our minds, it is easier to not do anything and expect everything to fall on our laps in a silver platter, instead of pushing ourselves towards the goal (whatever your goal may be). If succeeding was so easy, everyone would've achieved success by now.
Pertaining to one's spiritual development, quitting is a result of not wanting to transform, change and overcome ourselves. When we quit learning the Dharma, or any religion in fact, we are indirectly saying that we know more than the essence of the teachings. We cannot let go our attachment to self, and focus on helping others and transforming our minds. When we have to give, we'd rather run. But when receiving, we fool ourselves thinking that we can give just as much or more. What is the purpose of life, if all we do is just quit, run and hide. Life in itself is a continuous game..how are you going to find the exit? By learning and doing something about it to actually reach that point..not by being flippant and quitting. And what is that path to bring you to the exit? - Dharma. If you keep quitting, you'll never find your way out of the trappings you created for yourself.
