There comes a point in time where everyone reaches the limit. Where you can't take the pressure of life. At such a point in time you make the choice. It's one of two things, live, or die. You're either strong in your conviction or you're weak willed and try to find the easy way out. That's how things go in life. You're either weak or you're strong. The strong carry on no matter what, and they don't always look strong.

Example, the guy who dispite his frail appearence managed to survive through a drug addiction although they were weak to first become addicted the inner strength did prevail and he's prooven that a desire to live a healthy life is greater than the temporary euphoric (pardon my poor spelling) sensation a drug brings.

Strength doesn't always mean physical, the strength of one's mental being can be such that it makes up in full.

When you realize that you infact have the strength inside, the rest falls into place. So next time you look in the mirror look extra close, and if the spark's there you'll know.
