what have been your greatest triumphs and biggest mistakes
Public employment is hard to get, very hard

let's say you need some help in order to get it, at least this is the situation in my country.
The challenge: get the job of Junior Researcher in a major Public Organization right the first time with NO HELP.
I will always remember as my greatest success the time I went to Rome and won the competition (several hundreds of applicants, many of them were "helped"

) just for fun and then left the job to the second one

. WOW, I still keep the papers in my secret box.
I would say biggest defeats, because the opposite of triumphs are defeats.
After that I will give you my opinion about mistakes.
The biggest defeat was in a basketball match 164-34. Joking, that was a true match and I remeber it very well, but was not the biggest defeat. There is a Waterloo in my life, and at the end of the battle I was so devastated that I could not shout out S**T as Gen. Cambronne did. I can't tell you here.
A mistake is a mistake only if you could act in two or more different ways.
Moreover you can't predict the future. For instance, did Carlo Ancelotti a mistake in Istanbul final ? Or Rafael Benitez ? Or Shevchenko ? Who knows ? Only at the end of the match "the winner takes it all" and "the loser standing small" but who could imagine before ?
Let's go to the biggest mistake: I really don't know, I make mistakes every day

Forgetting that every single minute of life is special and unique, that's my big mistake. If I knew, I would have spent more time with my grandparents, they passed away too rapidly and too soon
