I am silent type person but there are some instances that make me chatty sometimes as well. I am not perfect, I also commit mistakes but that mistakes lead me to accept and learn from it which improve the poor quality of myself.
Everything goes up and down. Sometimes, it seems we can't handle things when we're down, the other way around we so much abusing when we're up. But those things are which we must take in balance. For everything we do, there is always adjustment or even the term control. Be strong but in the good way. Not as much as perfection but atleast a better one.
As a future teacher, I do believe teachers are the roots of all profession which makes me more hearten.
