Determined or Stubborn?

When I was younger, my family had a swing set complete with monkey bars, a slide, a couple swings and a glider. A glider is sort of like a see- saw but you don't go up and down so much as you glide back and forth.  It's meant for two small kids and has two vertical, parallel bars about that were six inches apart. I was, and still am, a stubborn kid. Not only am I stubborn, I also have a touch of ADD so I tend to do things without thinking them through. Remember this, it's an important part of my story.

One day, when I was about four years old, I was playing on the swing set by myself. We live out in the country and had big dogs that kept away wild animals; I promise my parents aren't negligent. I really don't remember much about that day, but I imagine I looked at those bars on the glider and thought, "I bet my head would fit through those." And it most certainly did. In fact, my head fit so well, it didn't want to come back out. I panicked. I'm sure I struggled with it for a while, couldn't get my head out, really started panic, thought I was going to die and started crying and screaming for my mom. I don't remember how I got out, but I did. I also don't remember how much time passed before I did it again, but sure enough, some time later I began eying those bars again. I have a deep seated need to conquer something that has once bested me. My four year old mind might have thought something like, "Glider bars, you may have won the first round, but this time I'm putting my head between you and it's coming out by my own power." I'm ashamed to say that had I thought that, it would've been a lie. I'm not sure how many times I did this (my sister says I did this several times) or if I ever conquered the glider bars. I only remember doing it twice. Knowing me, I probably did do it several times. So tell me, was I being stubborn or was I just determined? How many times have you gotten your head "stuck between the bars"?

"Don't You see how wonderfully kind, tolerant and patient god is with you?... But because you are stubborn and refuse to turn from your sin, you are storing up terrible punishment for yourself... He will give eternal life to those who keep on doing good, seeking after the glory and honor and immortality that God offers." Romans 2:4, 5, 7
