Not at all. Becoming an entrepreneur is not about your age but whether you have the drive and creativity to make it happen. When I graduated from college, I had no idea how to really start a business so I ended up working in a cubicle at a dead-end job. I knew inside I wanted to be entrepreneur so I started testing the waters starting side businesses in my free time. ( Fitness training, selling real-estate, blogging etc.)
I learned a ton, had some small successes but never made it big. The key though was, I had the fire inside, kept learning and kept trying.
It took me until I was 33 when I finally launched the successful company I lead today. Had I launched it when I was younger, I simply wouldn’t have had the real world experience needed. Even now in my 40’s I keep learning every day.
I think an older entrepreneur can definitely succeed if they have the drive inside to make it happen. The fears I see are that many times, older potential entrepreneurs are more risk averse and have more obligations than recent college graduates. This is totally understandable.
Here’s my advice if you want to test the waters
Try a side business. (The benefit of this is that you get to try the entrepreneurial world in your free time.) Another good reason is that you’ll likely be tired from your regular job and finding time for your side business will test your ability to push on. In reality, becoming an entrepreneur will be much tougher than your day job. You have to find the energy, drive and passion even when you’re past the “fun” stage of starting a company.
