Like a boulder

Stand away from the cliff...
You could fall off.
Destroy your gun before it goes off.
Give way on the street before an on coming car hits you like a falling boulder.
Don´t go halfway and be a quagmire soldier.
Don´t speed or snore or drink at the wheel, it could steer you to @#$%.
Your coffin heavy on your brothers shoulders.
Don´t be converted to being a bigot, as extreme views holders.
Don´t lie too heavy or blunt people´s ears with the truth.
Stay cool but don´t grow cold.
Keep a drop of real and don´t giveaway your authentic.
Cause you´ll be still rolling like a boulder, when your heroes have all sold out.
