Life is short; Seek your enlightenment

Today I wished someone close to me a birthday wish. I said, "Happy Birthday!" but it comes with a short message which says "Life is short. Seek your enlightenment." I told him I hope he knows what it means and I am confident he does. At least it will linger in his mind for a while. I think this is one of my most meaningful birthday greetings I have ever wished anyone. That short message basically is a reflection of my own thoughts for myself. That's what I am feeling right now. Feeling vulnerable and that time is running short. I don't knoiw why.  Lam Rim setting in? Or am I just getting old? I don't know.
