Maslow's Hierarchy of Needs is a system that lists the needs felt by every human being, in order of ease of accomplishment. Our basic survival (physiological) needs (food, water, shelter) are on the bottom. Next up is our safety needs (being able to live without fear of danger), followed by love/belonging needs (the need to have people who you support, and whom support you). After that comes esteem needs (the need to be supportive of your own choices). Finally, at the top of the list is the need for self-actualization. This is the need to feel like your life has significant meaning, and that you have done something for the greater good of humanity. This is a rare need to meet.
