Be productive - have a purpose, help others
A lot of people come to the depression support room saying they have no purpose or they're not worthy. Well if that's the case - why not be the opposite? Productive - life purpose to help oneself to the right place and help others.
This ties into altruism - egoistic -> optimistic. Once you help yourself enough - taking care to put oneself together (as value is based on what's around a person in addition to oneself) to increase one's worth -> be able to be whole (from helping oneself enough) to be able to help others. Once someone maxes out of taking care of themself enough that they don't need help - then they can go beyond oneself to help out the world - where the real help is needed.
For me - as long as I provide more than I take - then that's how I'm worth living.
What's stopping everyone from achieving that (where they get annoyed, etc. from hearing it or 'can't' or don't want to (like it's too hard)?
