What could a lay follower do to increase his zeal to become a monk? I wasn't lucky enough to be born in a Buddhist society and I only discovered Buddhism late in life mainly because of my innate dissatisfaction with life as a whole. 

Actually, I was born into a middle-class family and life wasn't that grim when I grow up, but even at my young age, I saw life as a journey that one has to pass through without his will. Funny enough, I used to envy old people because I thought that they are approaching freedom which is death. 

Obviously, I was wrong, death according to Buddhism is just one step in the cycle, I mean for those of us trading the circle of Samsara. 

Now, I'm convinced and I have faith in the teaching of the Buddha, but I sometimes fear that I'm too old to abandon the world and become a monk. I'm in my mid thirty have I missed the boat?

I have vowed to follow all precepts stated for the lay followed, however, I don't want to feel comfortable in the worldly life and I want to maintain my zeal to become a monk, if not now may be in the next life. 

What should I do friends? 

Many thanks.
I could easily have written your query. At this time however there are a few differences which may be helpful if shared. 

Am in my mid 40’s. Never thought that it was actually possible. Met a Venerable at the local Vihara who stated otherwise and has taken me under his wing so to speak with ordination to be the outcome. Yes, it’s a long road, lots to learn. But if it’s truly in your heart, it will be. Make yourself visible and learn as much as you can from as many as are willing to share. Have you decided upon a school of thought? So much to consider.

Please forgive for giving what equates to being advice, but the same is also my personal experience. Hope this is helpful in some small way.

All the best to you.
