i believe that the purpose of humanity itself is to advance our civilization. that suggests that everyone should contribute to that, which further implies that every contribution matters, no matter how small. you tried something, and it failed. that's fine. ideally others have an opportunity to learn from that, but even if not, at least you learned something, and you can use that learning for your future. the goal is not to create the greatest possible impact, but to learn and make the most of the resources available to you. it could be something small like if you are a lawyer having one out of ten clients pro-bono or for a very low rate for people who could not afford a lawyer otherwise. find an area/place/people that need help, and then help them.
