Fear and worry are the worst enemies.. But even after knowing it, you tend to afraid and worry about something when you come to know that it is out of your hand to control. At least in those cases it is acceptable because your fears and worries come out of the thoughts that you couldn't do anything about the situation..
But some people still worry about few things even though they know that they can do something about it.. They knew that they can change things if they take effort. But they don't do it. I don't know why.. I pity them..
When you know that there is something to worry about, don't you think that you gotta take some steps to bring the situation that can keep you comfortable (if not corrected, at least to have a feeling that you are on top of it to handle)??? God, why do people just sit and worry without doing something about it..? I pity them.. I really do..
