It’s not a big break. It’s, more likely, a smaller one that has compounded over time into something meaningful.
Your most important break, therefore, won’t look like anything special, and certainly not big. But you’ll notice it when you see it—it’s more accurately called your big start.
So remember this, if you spend too much time looking for your next big break, you'll be stealing your opportunity to do your best work. Focus on what’s big, now, it will catch up to the future soon enough.
