Point in case:
Get what you want. The chances that what you want will be handed to you are slim to none. You don't want to live your life wondering what it would have been like if you did more.
I've gone through some very stressful months lately (about 8 months total, to be exact), and even though I thought it would be easier to give up, I kept going. I kept working on myself; my goals, my body, my mind, and my surroundings.
I'm very far from where I want to be in life, but it's good to understand that the road isn't at a dead end yet for me :)
Same with you! :)
