"The more often — the better." Is it possible to say that?
Solution 1:
This is how I would stylize it:
"You should do this -- the more often, the better."
Other phrases that mean similar things:
You should do this as often as possible.
The more you do this, the better the results.
Results scale with use -- the more, the better
Etc.
Solution 2:
Yes, “the more often, the better” is correct.
