Does a career have to span a lifetime? I don't think so. Years ago, people chose a career path and stuck to it through their entire adult life. Not so today. The choices today are many and varied and, if you're lucky (and work your ____ off), you can enjoy the rewards offered by a number of different careers.
Today I am a children's author, however the path I took to this destination was a very crooked one. I began my adult life as an elementary teacher. For many people, this is a lifetime career, and I truly admire those who are dedicated to shaping young lives. However, after a few years I had another calling - horses. We moved to a farm and I became a horse trainer/riding instructor/show rider. This was backbreaking work (literally), but living on a farm taught our kids so many valuable lessons about life. To shorten a very long story, after my third back surgery the time had arrived to hang up the stirrups. So, what to do next? Write cookbooks, of course! I loved to cook, and healthful cooking was one of my passions. I ended up writing some of the industry's first lowfat cookbooks. This was great for 10 years or so. I traveled the country teaching cooking classes and lecturing anyone who would listen about the benefits of healthy eating. However, I really do love antiques and when I found that I was accumulating more than our house could hold, we faced a decision. Do we start hanging pictures and "stuff" on the outside of hour house or do we start selling some of our treasures? If you sell some, there is room to buy more. You guessed it. I became an antique dealer. But that was not the end of my careers. My life (and maturity level) were evolving along the way. I had "accumulated" ten grandchildren and soon found that my career was about to go full circle. My love for children's literature came rushing back, my love for children blossomed, and here I am today - a real live children's author. I think this may be my last career, and I feel that it is definitely the best so far, however I have learned to never say "never".
The point in all of this is, to me, loud and clear - Follow your dreams! Get excited about trying something new. Be brave. Go for it!
