Two of my favorite quotes are:
“The best way to ensure that lucky things happen is to make sure a lot of things happen”
“The harder you work, the luckier you get”
You greatly increase the number of opportunities you have for “getting lucky” by increasing the number of opportunities you give yourself to get lucky.
It’s amazing to think about how many opportunities I’ve been presented with and great people I’ve met just as a result of putting myself out there.
I like to call it “saying yes” — being receptive to new opportunities. When a friend invites you to a random party, say yes. Instead of watching tv at home, go out and do something.
When you’re really busy you can’t “say yes” to as many things. You have to be more selective with your time. But I still try to do things like taking the occasional coffee meeting with someone I don’t see myself working with right away if I see potential for further down the road. Or maybe they know someone I’d want to meet.
Bottom line: “say yes,” go out, organize stuff, and otherwise put yourself out there to increase your chances of getting lucky.
