Not too long ago someone stated that true happiness came from the absence of desire, and attributed the idea to Buddhism. I can't see that.
All of the things that drive me stem from desire: I want my family to be happy, and I want success in writing as it's all I've ever really wanted to do. What I want keeps me looking forward, and makes me eager to get home at the end of the day. It vexes me at the same time, but I'd rather have frustration and longing than nothing.
And I hear Morgan Freeman's voice in the last lines of The Shawshank Redemption, "...I hope. I hope."
And the alternative is withering:
"I feel the autumn fail - all that slow fire
denied in me, who has denied desire."
from "The Sequel" by Theodore Roethke
