During times of significant change, it's natural to lose sight of what truly matters to you. Your priorities shift, your focus shifts... and with it, the sense of purpose you relied upon.

Because we are, in large part, what we do... it's natural to feel uncertain and adrift.

If that has happened to you in recent weeks (which surely, to some degree, it has), here's a simple way to remember what truly matters to you.

Think about the best compliment you ever received -- the one that speaks to who you truly hope to be.

(This is the second of a series; the first featured Michael Hirst, the creator, writer, and executive producer of Vikings.)

The one compliment that stands out most speaks to a deeper meaning about who you try to be and what you try to do -- going beyond the (however exceptionally) superficial to strike a genuine chord inside you.

That one compliment reveals what truly matters to you... and what you need to stay focused on, especially in tough times.

This installment comes from Kyle Busch: Two-time Nascar Cup champion, founder of the energy drink brand Rowdy Energy, co-founder of the non-profit Samantha and Kyle Busch Bundle of Joy Fund that provides grants to couples struggling with infertility... Kyle is widely considered to be one of the most talented drivers in the sport's history.

Here's Kyle:

The most meaningful compliments I've gotten lately regard (son) Brexton. From Brexton's teachers, his karate teacher... (they'll say) he's a leader in class, he helps some of the younger kids, he's very patient...

... and he's nice. He's nice to other people.

That tells me we're doing something right in helping Brexton learn and grow, in teaching him well... and is something many people probably wouldn't believe about me. (Laughs.)

Clearly racing matters to Kyle; he's one of the most competitive people you'll ever meet.

But what obviously matters more is family.

What Truly Matters to You?

Odds are, the best compliment you've ever received regards not just what you do, but who you are -- especially to other people.

When we evaluate our lives, we think about whether we're heading toward our ideal selves, becoming the person we'd like to be. Those are the regrets that are going to stick with you, because they are what you look at through the windshield of life. ...

... for most people, those types of regrets are far outnumbered by the ways in which they fall short of their ideal selves.

What will you someday most regret? Not doing the things that help you become the person you most want to be. 

The best compliment you've ever received reveals the person you most want to be.

And can serve as the perfect reminder, especially during difficult times, of the things that matter most to you.
