Expanding Horizons. Deliberate Effort or Reluctant Choice?

A wise man had once shared his wisdom by saying "Zindagi mai apne daayre bade karna bahuth zaroori hai" which loosely translates to "In life, it is crucial to expand your horizons". What initially seemed like a cliche has recently got me contemplating about it.

I have come to realise that there are two distinct ways in which a person's boundaries expand: 
1] a conscious choice of stepping out of their comfort zone or
2] where one waits for life's unpredictable events to get in the way and makes it a necessity.

You could consciously invest in your health and well-being, or you could wait for adversity to push you toward transformation.

Likewise, you could actively embark on a journey of self-improvement, broadening your skill set, or passively wait for external forces to compel you into change.

Either way, you get to learn new things and expand your way of thinking. 
So, what method are you choosing in life?
