Wow... what a good question. I don't think any of us who've been kickin' around for a few years would trade in our life experiences. After all, they are what make us who we are. The things we have gone through help to define who we are and what we believe today.
I know that if I had decided to become a medic 20 years ago, when I first got my EMT cert, I would not have had the opportunity for the myriad of amazing experiences I gained. I know I wouldn't have lived all over the country, I wouldn't have met the people I've met and, most importantly, never learned what I've learned as I've matured. Looking back, If i became a medic in 1989, I probably would have been a fair medic, but stayed a stagnant one, living in the same small town I grew up in, thinking that our way was the only way, "'cuz that's how they do it here."
Not now. I've traveled, I've learned, I've grown.
I'll be 40 next year and feel like I'm just starting to really learn.
After working in a separate career for just about 2 decades, I can say that while I wish I had kept my EMS certs current over that time, I don't regret one minute of my past ... and I'm excited to keep throwing open new doors in the future as I grow in the profession of pre-hospital care.
