I agree with you Joao and itlktiv. Regarding myself, it took quite a time to learn meaning of some wise words (don't know who wrote them) but says something like: God, give me wisdom to solve what I can, give me acceptation to what i cannot solve and give me the wisdom to find the difference of both. It is absolutely true. Whatever you can solve, great - bingo! What you cannot, learn to deal with the unsolved, and never get stressed for that. Stress kills and if by worrying we can make something or solve something, then let's worry all us, but then we shall be losing time, energy etc. Hope this has helped you and hope some others can think twice that too much worry does not lead just that to nowhere, life is one and deserve to be lived as it: only once. Have a very good Sunday!
