While I was browsing through birthday cards, one caught my eye. It read: “The difference between 29 and 30 is 10 years.”

I cracked a smile.

Turning 30 isn’t the end of the world or anything. In fact it’s just the beginning of a better, wiser you. But is there anything quite like the young, dumb fun of your 20s and the growing pains that come along, too?

I’m sure there isn’t, but I am ready for the next chapter.

Today I happily turn 29, finishing off the decade of my extended adolescence.

Twenties are filled with almost as much angst as the teenage years. You’re still figuring yourself out, finding fertile ground to stand and build on.

You work hard trying to secure a successful career. You play hard at night and maybe squeeze in more work and find sleep when you can.

As time goes on, your priorities change. Sure, you might still like video games and late-night happy hours. But other things start creeping into your mind, like preparing for the next stage: mortgage, marriage, kids.

But before those cards are dealt and real responsibilities settle in, I’ve decided I need to take advantage of the youthful freedom I still have. Sure, my 20s have been fun but also very career-focused. I never found the time for audacious.

I’ve never been out of the country.

I’ve yet to see a Broadway show.

I can’t make my favorite dessert from scratch.

Do I need to get busy living or what? Some people have their bucket lists, the things they want to do before they die: bungee jumping, continent hopping.

But it’s not too late to have a bunch of things to get out of the way before the age of 30 — use a passport, go on a wild shopping spree, dye your hair some unforgivable color?

CNN has a series focusing on people under 30, Young People Who Rock. Last year it featured Jen MacNeil, a blogger who decided to send off her 20s by doing one new thing every day until she turned 30 and documenting it (jen365.blogspot.com).

I’m not as daring as Jen, so I doubt I’ll plan a daily adventure. Instead I’ll set my sights on 30 things to do before my 30th birthday.

Some of them will be big, like going overseas. Others might be as small as milking a cow. I’m open to suggestions.

I have a lot to learn, I know, but before I say hello to 30, I’d like to master the art of living life to its fullest. I’m not trying to just have a happy birthday. I’m hoping to learn to seize the day. Every day.
