Plant for Yourself
The word self is the prefix and we are free to add either "less" or "ish" after it. If we add "ish" the word becomes selfish which means a mean person who thinks of his own means only. It is dangerous because it costs so much that sometimes it becomes impossible to pay. We can think of the nature which gives us oxygen(life gas)for the free but we are so selfish that knowingly or unknowingly we destroy the it and ultimately we have pay a big cost for the same oxygen at hospital. If we don't pay, life is the cost. Hence let's add "less" to self and be selfless (come and workfor the nature).
