Goals more like Milestones

Goals on the long term seem to difficult to accomplished, at least to me, so for me it is better to break that goal into milestones. What I would really like to accomplished, the first milestone that I want to set, is probably to be less selfish and think not of what the others can do for me but what kind a I do for the others, be that in class, my home or with my coworkers (even though I can't say they are coworkers), well my friends from the "job". The second milestone would be to try to benefit the others through my work and I don't mean that in only approaching them but to actually change their realities and mine too, a social change. The overall goal in more or less words could be just to do a meaningful social work.
