The most important thing you can do for yourself and your race is keep your own life in order. You can and must become focused, disciplined, reliable, and, to the greatest possible extent, happy. Do people in your life tend to trust and respect you? What does your family think of you? Are you capable of raising self reliant children? If you can't achieve such things for yourself, then the chances are very high that you’re not ready to make a difference in the world, either online or in real life. Because how can you make a real difference for the race, for the lives of many, if you can't even make anything of your own, individual life?
Always remember: we live in first world countries and have opportunities that most people born on this planet don't. Things aren't as good for us as they were for our parents. But billions of people in the third world would still kill to have the opportunities that you do right now. So take care of yourself! Work your ass off, every day, to build a good life for you, and for your family. Clear your mind of self destructive thoughts, be nice to yourself, and keep yourself focused on realistic goals. Work hard, but also do fun and wholesome things with real people, in real life. That is very important. Never let anything from a screen take away from your real life.
