You've probably heard this saying before. Maybe it was said by a girlfriend approaching her 30th birthday. "30 is the new 20" is something us 30-year-old women tell ourselves so we don't feel old or depressed as we see our 20's fading in the rearview. But is that the complete truth? Or is there more to it?

I actually believe that 30 IS the new 20 and no, I'm not just saying that because I'm 32. I would even go as far as to say that 40 is the new 30! Are the hands of time turning backward or is it our mentality that's backward?

I think there's more to it.

In the 1990's it was all too common to see young women graduate high school and forgo attending a four-year college to instead marry their high school sweethearts and start procreating. By age 25 they were saddled with two or three kids, a white picket fence, and a mini-van. Life felt complete. Or did it?

Things drastically changed in the next 20 years. Attending college became a must for both male and female graduates alike. College diplomas were handed out alongside student loans that for some, would take years to pay off. One way to save money was to live at home with your parents for as long as they'd let you. This meant instead of being married with kids and a mortgage at 25, young adults were sleeping late while their mommies cooked them breakfast and folded their laundry.

Most people decided to secure a well-paying job and start chiseling away at their mountain of loans before even considering marriage. This pushed the newlywed age into the late 20's and even early 30's. A 2013 survey showed the average age for women to marry as 27 and men 29. I'd argue that 4 years later, the age has increased even further.

With life not getting underway until your 30's, I believe older individuals are adopting a more youthful mind frame. This means anything is possible at 35, 45, and even 55! I know women that feel stronger, healthier, sexier, and more productive as they approach 40 than they ever did in their 30's or even 20's!

Maybe it's because women know what they want and are realizing that age is just a number. The limitations we place on ourselves often live only in our minds. With a little positive thinking and determination you can achieve anything at any age.

So try not to view your next birthday as impending doom or a sign of life passing you by. instead, take on each new year with a new goal and a fresh, positive mindset. You'll be surprised with how much you can accomplish!
