i don't have enough

“You think you have plenty of time?” he repeated.
“Plenty of time for what, don Juan?”
“You think your life is going to last forever.”
“No, I don’t.”
“Then, if you don’t think you life is going to last forever, what are you waiting for? Why the hesitation to change?"
“Has it ever occurred to you, don Juan, that I may not want to change.”
“Yes, it has occurred to me. I did not want to change either, just like you. However, I didn’t like my life; I was tired of it, just like you. Now I don’t have enough of it.“
--Don Juan
