Recently I came across the Dalai Lama’s "18 Rules of Living,” which he shared with the world at the beginning of the new millennium. Here, 18 years later, it seemed relevant to revisit them.

In particular, I was struck by his rule: "Judge your success by what you had to give up in order to get it." At first I thought, "What?” As women, for example, many of us had been told umpteen times that we couldn’t have both a thriving family life and a successful career. Fortunately, that has been changing (although I still wonder why men were exempt from that contradiction!). Surely the Dalai Lama, that fount of compassion and love, didn’t mean we should judge our professional/job success by the family life we short-changed? Or vice-versa. Or that we should judge our success in either domain by the abuse, negativity or other unpleasantness that we stoically put up with in order to make it all happen?

That just didn’t square with what I know of the Dalai Lama’s philosophy. So I meditated on his rule, let it float around in my consciousness, until it hit me. I know exactly what I had to give up in order to succeed! My belief in impossibility, my doubting of my own talents, my fear of failing.

I remember vividly the first time an attorney asked me some 30-odd years ago, in my capacity as a trial consultant, if I could conduct a focus group for him. I’d only been a trial consultant for a couple of years, my experience was primarily with preparing witnesses for trial, and I’d never even heard of a focus group. But I needed to put bread on the table and keep a roof over my head, so I vaulted right past my insecurity and fear and said, "Sure!" I promptly scurried around gathering as much information about this mysterious thing called a "focus group" as possible, which was a very different challenge back then given the non-existence of the internet. It worked. Conducting focus groups became one of the cornerstones of my trial consulting career.

And then of course, there’s when I went back to ballet at 65. I looked with longing and envy at the younger students practicing their splits on the floor thinking, "I could never do that." I had to give up my "It’s impossible" and "Never gonna happen" to even get down on the floor and try. Now, I can finally do the splits with my right leg forward, almost there with the left. Give me a little more time and I’ll have both down!

What do you have to give up in order to succeed? What fear, insecurity, impossibility ruins your chances of the dream you so desire? Not enough time, not enough money, not enough talent, not enough resources, not enough support, not enough whatever! It’s those beliefs in limitation that we must give up in order to succeed.

There are endless examples online of people who’ve had to give up those beliefs to achieve their dreams. To take just one, Jake Olson, a blind football player, with two years of high school football and two years of college football behind him. He snapped the ball last fall for the final extra point that gave the USC Trojans their 49-31 home victory over Western Michigan. Imagine the limiting beliefs Jake must have "sacrificed" in order to snap that ball. A blind football player? Come on! And as his coach said, his wasn’t a "charity case," but that Jake was the player best suited to make that play.

Time for you to make your play. Give up whatever limiting beliefs you find that stand in your way, and enjoy your new-found success.
