What is Missing?

Once, twice, thrice,
Until when could this end?

I’d been here and there,
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 recipes 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.
