“We have a saying in Tibet: If a problem can be solved there is no use worrying about it. If it can't be solved, worrying will do no good.”
“If a problem can be solved it will be. If it can not be solved there is no use worrying about it.”
“If the problem can be solved why worry? If the problem cannot be solved worrying will do you no good.”
“If a problem can be solved, there is nothing to worry about. If it can't be solved, well you can always buy chocolate :)”
“If you can't solve a problem, then there is an easier problem you can solve: find it.”
“Don't worry so. Regret will only make you lose sleep, not solve the problem.”
