While not all of us are graduating from college this year, it’s safe to say we are all graduating from something in our lives. Whether it’s old habits, homes, jobs, or even parenting, we’re all graduates to some degree. (No pun intended.) So why let new college grads hog all the wisdom? The following quotes highlight poignant life lessons we can all learn from the 2014 graduation speeches.

1. Bill Nye: Knowledge can be acquired anywhere.

These were the words of Bill Nye, who gave this year’s commencement speech at the University of Massachusetts Amherst. Considering the source of this lesson (everyone’s favorite brainy scientist), it’s safe to say it is true. It makes perfect sense when you think about it. The world is filled with infinite diversity, perspectives, and unique experiences. When you meet someone you don’t like, challenge yourself to learn something from them.

2. Charlie Day: The most fulfilling things in life come with risk.

While you may not have expected the quirky, illiterate janitor from It’s Always Sunny in Philadelphia to share wisdom, Charlie Day delivered this brilliant advice to Merrimack College’s graduating class. Day also spoke about fear and acting in spite of it. The driving point of his speech was to not let fear become a barrier.

3. Bill Gates: Optimism is not irrational.

Bill Gates spoke these words at Stanford University’s 2014 Commencement. After a heart-breaking account of his trip to a diseased and poverty-stricken town in Africa, Gates confidently gave this advice and spoke about the importance of innovation. Optimism is not naive, and sometimes hopelessness can be an irrationally negative perspective.

4. Peyton Manning: Being a beginner is not a weakness.

Peyton Manning delivered this clever remark at the University of Virginia. Echoing the theme of Bill Gate’s quote, Manning is saying to disregard the naysayers, while maintaining faith in your own innovative ideas. He went on to talk about being a newbie, and how it doesn’t eliminate you from being able to contribute value. Well said.

5. Jim Carrey: Choices are made from love or fear.

Of course there were plenty of jokes in Jim Carrey’s commencement speech, but this was one of his most notable statements at the Maharishi University of Management in Iowa. “Fear disguised as practicality” is the key phrase. How many of us live our lives this way, avoiding certain dreams because they “just couldn’t happen?”

6. Rainn Wilson: Happiness doesn’t exist in a vacuum.

The delightfully quirky Rainn Wilson gave this advice at the University of Southern California. Comparing fleeting happiness to blood sugar swings is a pretty genius way of saying “don’t fall for the hype.” Personal possessions, money, or other self-focused versions of happiness are about as reliable as cotton candy for a diabetic. And in case you were wondering, eudaimonia is basically Greek for happiness. (I had to look it up.)

7. Melinda Gates: Hardship spawns our greatest efforts.

These are Melinda Gates painfully truthful words, spoken at Stanford University’s graduation ceremony. After telling a personal story of interacting with poor AIDS victims in hospice, Mrs. Gates extracted the positive, much like her husband did in his speech. There’s nothing more motivating than hardship – especially witnessing the hardship of others.

8. Marc Benioff: The secret to life? Give stuff away.

Although these are probably not the words you’d expect from a CEO, Marc Benioff, CEO of Salesforce.com, said just that at the University of Southern California. Coming from someone with wealth and a successful business, this says a lot. You can feel the certainty in his words – he’s been around the block and wealth isn’t everything.

9. John Legend: You can’t be happy with yourself if you’re not even being yourself.

Ask a soul singer the meaning of soul, and you might regret it hours later, when they’re still talking and philosophizing. Luckily, musician John Legend kept it concise at the 2014 University of Pennsylvania. This speaks to the idea that everyone “belongs” somewhere. Everyone has a passion, gift, knack, or whatever you want to label it. Maybe you already have an inkling as to what your’s is.

10. Parker Mantell: Doubt is more of a setback than actual setbacks.

You probably haven’t heard of Parker Mantell, as he’s not famous. He is, however, the inspiring student who gave the 2014 graduation speech at Indiana University (which is now going viral). Mantell had the courage to give this epic speech despite his stuttering problem, an obstacle he mentioned during the speech. We can all circumnavigate our failures and setbacks in one way or another, but doubt is pervasive. It will eat up any motivation we have, limiting our potential until we silence it.
