Remember to be your best.

I’d like to know if the word “self” is omitted after the word “best” in this sentence.

 

[Barque]

I suppose you could read it that way.

I'd have taken it as a sentence by itself without any omission.

"Failure is an opportunity to try something new."

If it's any kind of opportunity it's an opportunity to learn from somebody's mistakes.

How about do/try your best?

 

[Tarheel]

Yes. "Do your best" is good advice.

Is “be your best” a set phrase and is it used correctly in the context in the OP?

No.
No.

No. It's "Do your best" that could be considered a set phrase. (Somebody once wrote a brief poem that ends "Best is what you can't do better than." )

I take it to mean: Remember to be the best version of yourself.

It's an awful sentence. I consider it incorrect. At the very best, it's a terrible model, for the purposes of teaching English to learners.

 

[Barque]

That's right. "Be your best" isn't really a set phrase but it's used. It just means "Be the best version of yourself you can".

Cross-posted. I don't object to it as much as the others seem to.

"Be your best" isn't really a set phrase but it's used.

I don't think it is.
