Life of a???

Life is sluggishly slow.
People routinely comment on how slow,
No one truly can know.

I try to speed, I really do,
A speeding ticket, I will ensue.
But alas, speeding is not true.

I simply pace along,
I really am rather strong,
Distances are short not long.

Can you guess what I am?
A hint perhaps, I am not a lamb.
Nor a camera, shortened to cam.

Nor a postage stamp on mail,
A bucket list, not a pail,
I am simply me, a snail!
