I have landmarks in my life that I'm aiming for, but meeting them isn't necessarily what will make me feel successful.
To me, it's so much more important to preoccupy yourself with the works, or the 'process', instead of the end-goal. Just putting yourself in an environment where you're constantly striving for stability, self-improvement, that sort of thing.
I'll be disappointed if I don't devote a chunk of my life to improving the lives of the less fortunate, for man-created reasons. It's intentionally vague because there's so many ways to go about it, and who knows how I'll get there. But at the end of the day I consider myself a fairly faithful person, and my testament of reverence and belief and love for God is my devotion to myself and my fellow human compatriots of all walks of life.
I'll feel accomplished if I'm satisfied with the work I put in, towards the end of my life. Thinks like companionship, family support, finances would all seemingly help me be the best person I can be, and thereby enable me to bring forth as many of my dreams to fruition as I can-- but God knows best. I'll work with what life gives me.
