what is it?

Some are given many
rarely you don't get any
some get only a few
what you do with them is up to you

There are too many to see
they stretch farther then the sea
and though they may sought
they cannot be bought

some are bland
while others are quite grand
some last way too long
but other's so short it's wrong

no two are the same
otherwise it'd be a shame

What is it?
What could it be?
though hidden in a tree.
The answer you may see.
that lies within me.

have fun searching the sea

(which is your mind of course :) )
