Do not use negative booleans, please

I hate negative booleans.

If any time, for any reason, you need to use a boolean variable (very common), please always think in positive.

You don’t know how many brain cells I have wasted interpreting code like this:

# Declare variable
no_update = True

# Use variable
if not no_update:
  do_something()

I mean… why not just write it like this?

# Declare variable
update = False

# Use variable
if update:
  do_something()

And time and again I keep on seeing that pattern… Seriously, always be positive please. And if you need to negate it, then just put a not operator in front of it, that’s why they exist for!
