Is this within my control?

When dealing with issues and things that come up, a good question to ask is “Is this within my control?”

I don’t like spending lots of time and mental and emotional energy on things that are not.  In the end, you get the rug pulled out, and you’ve wasted lots of time and wind up with heartbreak and disappointment.

Instead, I work on things that are within my control.  I invest my time and make it work.  Over time the sphere of things that are within my control grows, and I feel like I am becoming a master of my world.

What are you working on now?  Is it within your control?
