Being successful is the circumstance of a few moments in time.
Those moments cannot be forecasted. They appear when they do, as a function of other circumstances. The way to leverage those moments is to be ready when those amounts arise.
To be ready means to be the best version of readiness that one can be. Maybe you're not 100% ready for that moment, but if you've worked hard to be at least 80% ready, others can help.
The imperative, therefore, is to optimize individual readiness at a given point in time. That is a product of everyday, honing and perfecting your craft. Putting in the hard work when no one else does. Challenging yourself each and everyday, pushing and winning each day.
To be successful, push hard everyday, perfecting yourself for that moment when it is time.
