Worry is one useless hobby, It fools us into thinking "maybe its got a solution", But in the actual sense, It changes nothing. Most things we get worried about don't even happen, Worrying is useless, Worrying isn't thinking, Worrying is worrying, Thinking is thinking, When you think,you try to find a solution, When you worry,well you just worry;and get nothing. Yes its normal to worry, Just not regularly, You might get mental sickness, Its no joke when people mention madness.
