You couldn't relive your life, skipping the awful parts, without losing what made it worthwhile. You had to accept it as a whole--like the world, or the person you loved.
We're all human, aren't we? Every human life is worth the same, and worth saving.
One hot afternoon during the era in which you've gotten yourself ridiculously tangled up with heroin you will be riding the bus and thinking what a worthless piece of crap you are when a little girl will get on the bus holding...two purple balloons. She'll offer you one of the balloons, but you won't take it because you believe you no longer have a right to such tiny beautiful things. You're wrong. You do.
Life is a one way road. You can choose to keep moving forward to new territory. Or you can choose to go in reverse because it is familiar territory, but then you get further away from ever moving forward.
