"It's so good until no good" - Samuel Liew

This means that something is too good, such that it becomes undesirable, because it created a bad situation - like a bad habit, or made someone spoilt, etc.

"Just do your best" - Samuel Liew
"Being a good listener is not only listening when another is speaking. You also have to correctly understand what is not said." - Samuel Liew
"We are not perfect, but that should not be an excuse to not do our best." - Samuel Liew
