You should contribute to humanity in whatever method or quantity you're able, and not sweat it too much. That doesn't mean you shouldn't try hard. It just means you shouldn't get too stressed out about it. Some people are fortunate enough to make huge contributions, other people make small contributions, and both are totally fine. You're doing great if you're contributing positively at all. We're all humans trying to make the world better. Even the ones that make it worse aren't to be blamed, they were simply unlucky genetically or environmentally. It has always been on the shoulders of the most fortunate to do the most important work. It's not any different today, except that a growing percentage of society is so fortunate. At the end of the day, we're all one human family and it's totally unimportant who did what to get us to the promise land. All humans can take rightful pride and ownership over the results of our collective effort.
