A half-truth is usually less than half of that.

I like half of you half as well as I should like, and I like less than half of you half as well as you deserve! - Bilbo Baggins

The truth is that we all have to do more things than we can rightly do, if we are to do anything at all.

Always do one thing less than you think you can do.

Less than half are coming from Siebel.

I don't know half of you half as well as I should like; and I like less than half of you half as well as you deserve.
