Be the one who is always optimistic and try to see the opportunity in every failure.
Do not be pessimistic just seeing failure at every opportunity.
People are optimistic to see donuts, while pessimists see the holes only.
You can develop the success of any failure.
Despair and failure are the two stepping stones to success.
There is no other element that is so valuable to you if only you would study and work it for you.
Look at each issue as an opportunity.
Only when the weather is dark enough you can see stars.
