If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
Dalai LamaThe real troublemakers are anger, jealousy, impatience, and hatred. With them, problems cannot be solved. Though we may have temporary success, ultimately our hatred or anger will create futher difficulties. Anger makes for swift solutions. Yet, when we face problems with compassion, sincerity, and good motivation, our solutions may take longer, but ultimately they are better.
