I highly recommend reading this entire blog post by Caterina Fake, founder of Flickr, the photo-sharing platform.
Just a few of my favorite quotes from the post:
"I've come to the conclusion that working hard, while never a bad thing, is not really the magic thing that leads to great inventions or successful outcomes."
"Working on the right thing is probably more important than working hard"
"We agreed that a lot of what we then considered "working hard" was actually "freaking out". Freaking out included panicking, working on things just to be working on something, not knowing what we were doing, fearing failure, worrying about things we needn't have worried about..."
"Putting yourself in the right place where information is flowing freely and interesting new juxtapositions can be seen."
If you have any good links to posts on working smart vs working hard please share them in the comments!
