At some point in life, people will evaluate themselves to see if they have been

a good child
a good student
a good boyfriend
a good employee
a good husband
a good father
a good grandfather,

evaluate their

performance
feelings
thoughts
ideas
actions

many a time, people will just be thinking that they did a wondeful job as long as nothing happen. Little did they know how the effects of these things happen unknowingly and the effects can be terrifying both mentally and physically.

perhaps it would be wise if one evaluate himself time and time again to make his life meaningful and fulfilling and treasure his love ones.
