JAMES CORDEN, Glamour

In just a few hours, James Corden will make his debut as the host of the Late Late Show, stepping into the shoes once filled by Craig Ferguson

But before he takes his permanent seat on the CBS set, the 36-year-old comedian, who relocated to Los Angeles with his wife and two children to take on the iconic gig, penned an open letter to American women in Glamour's April issue, weighing in on everything from one-night stands to landing your dream job to cutting yourself some slack. 

"A lot of advice got thrown my way when I became a husband and then a father to a baby girl just five months ago; some of it was shockingly good and even helpful," Corden begins in his missive. "So for anyone else I can help out there, here's some of the best stuff I've learned about love, confidence, and generally being a decent person in the world." 

Here are our favorite words of wisdom:

• "Realize that 'meaningless one-night stands' aren't meaningless. I believe, deep down, that all the ones I've had have affected me. Some of them were good, most of them were bad, but they still had meaning. (Everything is always about sex. But sex is always about something else.)"

• "Get your heart broken; you'll be better for it. Trust me on this. My heart wasn't ready to truly love someone until it had been broken. If you're in a place of heartache, remember that when you lay your head down tonight, somewhere else a person you may have never met is doing the same. And that person is going to love you more than the last one ever did. So look after your broken heart tonight; tomorrow could be the day it starts to mend."

• "That said, do not date a guy who takes gym selfies. The only thing worse than vanity is male vanity. I recently moved to Los Angeles, and I'm gobsmacked by the volume of male vanity knocking around. Is it sexy? I'm not sure it is. What's sexy is making a lasagna and eating it with your partner."

• "Respect your body. It is what it is, so embrace it. Love every scar, ripple, and imperfection, and you won't need others to do it for you."

"Forget about age. I remember turning 25 and saying, "I'm so old!" Now I look back at 25 as the golden days of my youth. And honestly, I think that when I'm 45, I'll look at 36—my age now—in the same way. It's not how old you are; it's how you are old."

"Cut yourself some slack. You're going to screw up sometimes, and there's nothing you can do about it. But what's important is not the when or the why, it's how you deal with things after. My advice? Meet it head-on and say, 'I f--ked up, and I'm sorry.' Make sure you mean it and learn from it, and it'll go a long way."

"Never stop believing in yourself. Everyone's a fraud, so take a deep breath and go for that dream job. There is no reason it shouldn't be yours."

"Try not to criticize. Everyone is, on the whole, trying their best. And if they're not, your criticism is just a waste of your time."

"Live in this moment. Everything in your past is gone and everything in your future is undecided. All you really have is this moment, right now. So be the very best you can be. Let yourself shine. If you always do that, your life is going to be great. I promise."
