Opportunity Cost

"Opportunity cost" refers to the fact that by choosing to do one thing, you spend time that could have been used to do something else.  That alternative way to spend time is the "opportunity cost" of  your choice.

I don't know about you, but (especially when I'm physically tired and feeling more selfish) I'm more likely to make poor choices about what I eat, what I read, what I watch, what I do, etc.  It's been helpful for me to ask myself "What's the opportunity cost?" when I'm inclined to do something.

Sure, passively watching TV would "feel" great right now.  What's the opportunity cost?  I'm sure you can think of other example situations.

Note: I'm not opposed to leisure and rest.  They are good and necessary.  But men, we need to know ourselves and push ourselves to our best.
