Read other people’s code
The best way to improve yourself as a human being is to absorb the insights of others.
Specifically for programming - read other people’s code!
I stumled across this nifty little method “all?” examining some FactoryGirl examples:
%w{ ant bear cat}.all? {|word| word.length >= 3} #=> true
%w{ ant bear cat}.all? {|word| word.length >= 4} #=> false
[ nil, true, 99 ].all? #=> false
