My father's lesson to me

My father have taught me few basic theories of life. At the end of which he told me that these theories are not universal. No one can predict that which one could be applied where.

Every situation would be different and would require a different solution. Where what i have tought you might not suffice.
You must yourself analyse the scenario which you are presented with. Read the man, glean from the situation. Look for the solution, if the theories work then imply them if they don't find your own way.
Every obstacle that you concur or loose would teach you some new lessons.

Emend those strategies and pass them on to the younger generation.
