Motive and opportunity
Sometimes attendees say a conference changed their life.
Perhaps.
If you changed your life as a consequence of participating in an an event, it is you who changed it.
Investigators, on TV at least, look for motive and opportunity for a crime.
For something positive it can be much the same.
Who had the motive? You had the motive to attend the conference, ask questions, perhaps propose a session around something you wanted to share, and you had the motive to do something with it after the fact.
The conference may have provided the opportunity.
In fact, you also supplied part of that opportunity for others, by bringing your questions, interests, observations and puzzles.
