We are part of an interconnected world. You cannot say you make no difference. You just can help someone who in future will do something big, we never know. Think in the butterfly effect. Just your existence now, make a disturbance in whole universe.
But I know how frustrating is to start the life in negative score. Every born-in feels the same. But you can always remember no matter how miserable your situation, always will be someone in a worse situation. This thought is a double edge sword, it brings consolation and perplexity at the same time.
