"I’ve been very lucky to have achieved a lot of the things that I dreamt of achieving as a young man," DiCaprio said in an interview with the Telegraph. "But, at the end of the day — and I truly believe this — it is not about achieving great wealth or success, because they don’t bring happiness ultimately. They really don’t. What matters is whether or not you’ve fulfilled the idea of having led an interesting life, whether you’ve contributed in some way to the world around you."

Don't be afraid of failure. —Beyoncé

Even the most successful people are familiar with failure. In a video for her self-titled album, Beyoncé explained how she dealt with loss and learned from it. "The reality is, sometimes you lose," she said. "And you're never too good to lose, you're never too big to lose, you're never too smart to lose, it happens. And it happens when it needs to happen. And you have to embrace those things." 

Know your limits. —Lady Gaga

When stopping by Yale, Lady Gaga described how she became unhappy after overextending herself and agreeing to deals she didn't feel strongly about instead of focusing on her own creativity and music. She started saying no instead of agreeing to everything, and found her passion again. 

"I feel sad when I'm overworked and I just become a moneymaking machine and my passion and creativity take a backseat," she said. "That makes me unhappy. So what did I do? I started to say no. I'm not doing that. I don't want to do that... And slowly but surely, I remembered who I am."
