Tikkun HaOlam is not limited to battling the klipos. It means, whenever I have the opportunity to make the world a better place with a tiny amount of effort, I do it. I pick up the random plastic bag on the stairs before someone trips on it. I scrunch down the garbage in the public garbage can (with that bag you picked up). If I can do something for someone else at a tenth of the effort it would take him, I don't even wait to be asked.
Hatzlacha!
