Quote for the week

Simplicity is hard work. But, there’s a huge payoff. The person who has a genuinely simpler system — a system made out of genuinely simple parts, is going to be able to affect the greatest change with the least work. He’s gonna spend more time simplifying things up front and in the long haul he’s gonna wipe the plate with you because he’ll have that ability to change things when you’re struggling to push elephants around. -- Rich Hickey
