The biggest mistake to me is complacency.

The biggest mistake we made at WordPress.com in term of infrastructure was buying servers.

Investors should invest on what they know. The biggest mistake is to invest on what they don't know.

The press keep asking me, 'What was your biggest mistake?' But if I had made a big mistake, they'd all be writing about it, wouldn't they?

That was the biggest mistake I've made. If I could do one recruitment over, it would be Adrian Zamora.

The biggest mistake a man can make is being nice and hence being fooled. The 2nd biggest ever mistake that a man can make is to think that the other person is nice. Today, people have stopped being nice.
