There are the highs and lows.

High
When praise is the light
That glides you down  
The corridors of life.
When you've been smoking
All night
Your in another world.

Low
You walk around unnoticed,
Scraps in the wind.
Peoples words pound the
Deepest walls of your self esteem.

High
Confidence.
Fire.
Ambitious.

Low
Depression.
Dark.
Pain.

But sometimes, there will come a time when you can't tell them apart.  
Where the difference between high and low in like trying to figure out if you rather freeze to death or burn to death.

No matter which you choose, they're both lethal.
