"Experience is not knowing what to do. It is about knowing what not to do"
This was told to me by one of the professionals of my field few years back, when I was with him doing some verification work.
Believe me!! as my (professional) experience is increasing day by day, I come to know more and more about "what not to do".
It is something like you do something new, make new mistakes , know about it and make sure you won't repeat it again. you will see that your what-not-to-do list is growing and so is your experience.
It is not only true in case of professional life. It is quite true for our normal life also. If one doesn't do the above in his routine life, he may not be considered as "experienced" even though he grows older day by day.
