Inspired by Paul Graham, I've listed some of my favourite quotes.
"Here’s to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes… the ones who see things differently — they’re not fond of rules… You can quote them, disagree with them, glorify or vilify them, but the only thing you can’t do is ignore them because they change things… they push the human race forward, and while some may see them as the crazy ones, we see genius, because the ones who are crazy enough to think that they can change the world, are the ones who do." - Steve Jobs
"Don't worry about what anybody else is going to do. The best way to predict the future is to invent it." - Alan Kay
"Premature optimization is the root of all evil (or at least most of it) in programming." - Donald Knuth
"And I like large parties. They’re so intimate. At small parties there isn’t any privacy." - F. Scott Fitzgerald, The Great Gatsby (Jordan Baker)
"Formal education will make you a living; self-education will make you a fortune." - Jim Rohn
"Don't let schooling interfere with your education." - Mark Twain
