We wish they happen to us as well.
Actually serendipities can happen to you.
However, every serendipity happens for a reason.
The reason is that you have prepared for it. You’ve done essential homework. Even tough you may not be aware of this.
To have serendipities happen to you, you can start to write down any random bits come to your mind and write them down. This is an essential process for serendipity.
The price of serendipity is the preparation.
Chance favors the prepared mind.
