How to Fulfill Your Second Half Career Dream

• A goal and a plan. Yogi Berra famously said, “If you don’t know where you’re going, you may not get there.” Let me put it this way. If you don’t have goals and at least some semblance of a plan, you’ll never get there. For one thing, you’ll be leaving things more or less to hope or chance, and you’ll need better odds than that. Then there’s your own inertia - tough to stop without a damn good reason.
• The entrepreneurial lure. Sure, I was proud of my career and the management level I’d achieved, but I had always worked in somebody else’s company, a corporation with a CEO, a board of directors, tons of employees, and a boatload of shareholders. I wanted to plot my own course at my own company. I wanted to be an entrepreneur.
• The need to test yourself. Even though I played a key role in the companies where I worked, including taking risks and achieving great rewards, I was still part of an executive team and there were so many success factors that accomplishments were really company or team accomplishments. I wanted it to be me, just me, taking on a new profession. I wanted to test my mettle on my own without a big corporate safety net.
• A dream. Although I loved high-tech and marketing, I actually had a dream that started decades before that career even began. Since I was a little boy I’d loved reading books, so much that I romanticized the profession. And now that I had something to say and a voice with which to say it, I wanted to put pen to paper and fulfill that dream.
