I am an odd number, and in my prime. But, most of me is even.

I am always ahead but never seen, I'm promised to all,yet belong to none You can chase me but never reach me, For once I arrive, I am already gone

All people hate when you tip me If I answer what's wrong then you doubt me I'm the one thing that will last forever If you know me you can't be that clever

I'm fastened with nails. I'm a means to arrive. I'm two to begin but I end as a five. My length is my own, not know globally. The most devious time is when something's a me.

View me with disgust But compute me you must Might make you sick I bet But you need to to catch the net
