poem, what is missing

What is Missing?

Once, twice, thrice,
Until when could this end?
I’d been in and out
But bitter is still what it tastes in the end.
Why can’t I get the best tasting ending?
Where can I get that one of a kind ingredient?
Should I deal with it like a Math problem?
Where is the given formula?
What am I missing?
When can I get that best equation ever?
How many scratch paper should I tear?
How many recipe should I burn and put to waste?
Sometimes, I just get tired.
And wanted to curl up and cry.
Ever since, keep asking why.
Haven’t found the best answer to thy.
