Comfort zones

Comfort zones
Who defines them?
Us? The situations?
Upbringing?
Limits we set for ourselves?
Maybe choices.
Willing decisions.
Growing out of them
Is fun yes.
But it is essential to decide
Which ones!!
But until you won't jump
How w would you know
The depth of the river?
The thrill in it?
What if it becomes a suicide?
What if it happens
The most amazing thing
You have ever come across.
The extremes are possible
In either directions.
In fractions
In fiction.
It's upto you
To decide
Which one to break through
From your intuition.
Comfort zones.
Who decides them?
We. For sure. Us.
