Explain this

explain this if you don't suceed then try and try again

"Explain this if you don't suceed?" "Explain this if you don't suceed?" That makes no sense. Ok, wait, it's succeed. And maybe he means "Explain this: 'if ...'" Yeah, that must be it. Ok, here goes: If you fail at a task (say, punctuating) then you should persist. Try, and try again, because eventually you will succeed. In theory.
