I just turned 55 — here are 10 life lessons I wish I'd learned a decade ago

• Life lessons come in many shapes and sizes, and often are learned the hard way.
• The older I get, the more willing I am to take risks. I wish I’d become willing to do that sooner.
• At age 55, here are 10 life lessons I wish I’d learned earlier in life.

Looking back on my 55 years, I wish the past me hadn't assumed the future me would be rich. I would have saved more.

Among the other lessons I've learned: A good haircut and a nice pair of shoes show that you take yourself seriously — and others should, too.

I try not to look back with regret, but here are some things I wish I'd known a decade ago.

Take time to pay attention to your health.

I had asked a doctor once or twice for help with chronic digestive problems, but they were stumped, so I dropped it. It wasn’t until I committed to spend whatever time it took to find the cause that I discovered I had a gluten intolerance, which probably started in childhood.

My health is immeasurably better since I gave up wheat, barley, and rye. And I learned the value of spending time on my health.

Wear sassy boots.

After a lifetime of frugal shoe purchases, I splurged on a pair of designer boots. It was the best purchase I’ve ever made. They have lasted much longer than less expensive shoes and they make me look arty and professional at the same time.

Never underestimate the power of an awesome pair of shoes.

No more bad hair days.

Your hair is one of the first things people notice about you. Since I sought out a stylist who understands my hair, I have something I once thought was impossible: good hair every day.
