There is an immense amount to be learned simply by tinkering with  
things.- Henry Ford
Most of skills I have acquired are becuase of application of the above  
philosophy. From my aesi days to training. From NAL to my present job,  
tinkering with tools has been the underlying truth.
Be it a new cad/cae software tool, or the trusty ms office, skills  
only develop once you begin tinkering.
So if you feel stagnant in your training, bored at the mundane  
assignments at your job, take up tinkering.
Treasure lies behind tinkering.
