Languages: The Good Parts

"Most programming languages contain good and bad parts. I discovered that I could be a better programmers by using only the good parts and avoiding the bad parts."
Douglas Crockford, Javascript: The Good Parts, p1

"Take an existing programming language and make significant improvements to it by making no changes except to exclude the low-value features."
Ibid p.99

So what do I leave out?

In C# I use public a lot, private a bit, internal almost never.
In Excel magic numbers, multi-level formulae

That's probably why I took to jQuery - the Write Less Do More mindset.
