It's a good attitude that seizing opportunity is something you could always try to do but it's certainly arguable luck plays a HUGE role in which specific opportunities show up.
There are countless examples and very famous and successful people will often point to all the luck in their lives. To name just one example Ed Catmull, president of Pixar and Disney Animation points out all the luck in his life in his Creativity Inc book.
Luck that Lucas decided to sell Pixar, Luck that Jobs bought it before it got disbanded. Luck that Jobs failed to turn Pixar into a computer company like he tried to do for a couple of years. Luck that Jobs was willing to sink so much money into a losing company IIRC 57 million before they switch to animation.

I'm sure others can name other examples.
