3 L's: Live, Laugh, Love ; which was most important?

My mentor told me to remember the 3L's:
1. Live
2. Laugh
3. Love
He asked me which was most important and I said LIVE. Because if you don't live, you can't laugh and love. However, he corrected and told me that LOVE was the most important because if you never find love, you'll never laugh and never completely understand the meaning of living.
