We all have our personal truths that we believe beyond a shadow of a doubt. It could be our faith, politics, or something on a smaller scale such as nutrition or how to live a good life. We could try to explain our beliefs to others and convince them with our words. But if you really want others to share in your truth, you must show them by your actions.
One of the books I am reading right now is Skin in the Game: Hidden Asymmetries in Daily Life by Nassim Nicholas Taleb. I’m am about halfway through, and though the subject matter might be a little over my comprehension level (a lot of google involved), I am doing my best to make it through. In the book, the author speaks of those who make decisions but do not have to live with the consequences. Think of politicians who never pay the consequences for their decisions. But the real heroes in the world are the ones who take the risks and live with the consequences, whether good or bad.
To have skin in the game of whatever philosophy you believe in, you must live it, not just speak about it.
