Maturity.

Maturity. Most consider maturity as a coming of age; an achievement of some sort or, of reaching a level of developement.

Think about it.. Maturity often involves obtaining opinions and influence from external sources, then, mixing it with that of one's ownself. Wouldn't that mean it is an additive, or rather, a contamination of one's personal style of thought? If so, does the 'maturity' really mean a significant input of opinion 'pollution' ? - I guess it all depends on the angle of viewing.
