What do you think about these activities? To pick up litter?

I think that everyone should pick up litter of other people thrown on the ground from time to time, for example while jogging or walking with the dog. I am also in for helping elderly and lonely people - it is a good deed, and it can really help them. I dont like to do tricks and dont do them as its dangerous. In my opinion, adults and teenagers also should help children as they cant do everything on their own as they are little. We should water the flowers, but I always forget to do it. I like raking leaves as it helps me to relax. I dont think washing off graffiti is always correct - sometimes graffiti is very beautiful. I like collecting secondhand books and repairing them. I am crazy about doing the shopping especially buying clothes.
