Life is all about making mistakes and learning from them. Some can be devastating, but getting to the other side can make you a stronger person. It takes a lot to overcome some of the hurdles that spring up in our path.
One of the things I learned over the years is that every one of those hurdles can be a defining moment. You just never know which one(s). It is also a hard truth that some of those hurdles are placed in front of us by others.
If you sat down and thought it over, how many hurdles have you placed in the paths of those around you? Sure, some might be very small. Barely a bump in the road as they say. But others can be crippling.
You might have placed those hurdles quite by accident. If that was the case, did you go back and try to help that person over, or maybe at least slip in and attempt to lower it? And if you did it on purpose, can you live with that? Did you do it out of malice? Jealousy? Or some perceived sense of self-righteousness?
If you took something you thought to be true and used that as the impetus for your actions and later discovered that you were wrong...could you be okay with your actions? Perhaps the easiest way to truthfully decipher that question is to turn the table on yourself and see if you would be okay with having those hurdles thrown up in your path.
We are a very reactionary society. Much of it (I believe) comes from not having to really ever interact with many of the people we so easily tee off on. Have you ever dealt with somebody in your life and then discovered YOU were the one who had it wrong? How did that feel? And then there are those warnings about being careful what you say since, once it is out of your mouth, (or fingers for this society of keyboard warriors) you can't unsay it.
Really, it can come down to a simple grade school proverb...it begins with "Do unto others..."
Just remember, if the day comes when you find you are wrong, make sure that all you dished out will fit down your own throat.
