Jack of all trades

When I got started in marketing I remember that I thought about one quote all the time:
“Jack of all trades, master of none.”
But over time I’ve started to think the other way around. Or at least in a middle term.
Of course mastering something is key. And if the thing you want is to get a job or be a freelancer, great, that’s the way to go.
On the other hand, if you’re an entrepreneur being a jack of all trades is a nice place for you to be. Knowing a bit about everything is great. Don’t think about its downside, but think about it as an opportunity. 
Jack of all trades sometimes just means that you know what sort of things can be done, and find someone who does them for you. And that’s a great way to be an entrepreneur.
