Breaks come to lots of people. The ones who already practiced are the only ones who can cash them.

Luck lands fairly widely, and mostly on people who are not in a position to use it. An opening only turns into something if there is prepared work behind it, because the window is short and nobody waits while you get ready. What looks like a lucky career is usually years of preparation meeting one ordinary piece of chance.

Since you cannot schedule the opening, work on the part that is yours: the skill, the portfolio, the thing you could show tomorrow. Keep it current rather than theoretical. When something arrives, the only question is whether you can deliver this week.
