Failing is another way of learning.  It teaches us what doesn't work and help us in streamlining our options. There's this kind of satisfaction one feels when one tried at something and failed than not trying at all. When i was in the university,  there was this high class lady i was interested in and was procrastinating approaching her because i was scared. The sad thing about procrastinating approaching her was that i was unconsciously shunning other ladies that was interested in me because of this very lady I've not yet approached.  I developed courage and approached her one day and the result was negative but i was very glad i did because a week later i met a very beautiful lady and we became very close. if i hadn't approached her the time i did, maybe i would have continued hoping and also miss the opportunity of meeting the lady i met a week later. So of a truth, failure a times, prepare us for what is ahead.
