Don’t expect to experience many serendipitous encounters if you do not also plan to take initiative towards your dreams and ambitions.
Serendipity, although spontaneous in nature, is triggered by action. It’s possible only through the joined efforts of multiple parties.
Sure, doing nothing could create a bit of serendipity, but is it the kind you want? Something happening to you, instead of because of you.
Create your own serendipity. Go out and build something.
