Global health equity champion Paul Farmer was a great doctor, but an even better human being

With age comes wisdom, or at least we hope it does. As we get older, we collect life lessons that we can pass along to younger generations, sometimes with lengthy stories, sometimes with quippy sayings.

Adages like "A penny saved is a penny earned," or "Early to bed, early to rise makes a man healthy, wealthy, and wise," have been part of our collective treasure chest of life advice for generations, but the aphorisms that spring from the experience of our loved ones and mentors are often the most meaningful.

Someone shared that they'd read and appreciated this old man's advice: “My grandpa once told me 'if you get on the wrong train, get off at the nearest station, the longer it takes you to get off, the more expensive the return trip will be.' He wasn’t talking about trains.” The person asked for more tidbits of wisdom from old folks and people started sharing sayings they heard from their elders growing up.

Here are some of the best "old man advice" sayings and how they can be applied in a person's life.

"You might miss what’s ahead of you if you keep concentrating on what’s in the rear view mirror."

Another commenter put it another way: "Don't look behind you, you aren't going that way." This adage is about not dwelling on the past. Many of us have a tendency to spend more time mentally in the past, rehashing old memories or being nostalgic for what once was, than we do in the present or looking forward to the future. There's nothing wrong with a little reflection, but if most of our focus is in the past, we miss out on the present. Rear view mirrors are for quick glances, not where our focus should be.

"Do the right thing, even if nobody is watching."

This saying is about good character and true integrity. If you notice someone drop a $20 bill and no one is around to see but you, do you give it back to them or do you pick it up and keep it? If you realize that a store didn't charge you for an item, do you point it out and make it right or do you allow the mistake to remain? There are opportunities each day for us to choose between right and wrong, and those choices really speak to who we are if they are made without anyone else knowing.

"Be nice to everybody you meet on the way up the ladder. You'll see the same faces on the way down "

Don't get cocky and don't burn bridges you think you won't need to return to. There's value in being kind for its own sake, but there's also the reality that being kind also makes people like you. When people like you, they're more likely to lend you a helping hand, and you never know when you're going to be in a position to need one. It's also a good reminder that you're not inherently better than anyone else just because of where you are in life. We're all constantly in flux, so it's important to stay humble and kind.

In other words, "Make all your words sweet because tomorrow you may have to eat them."

"One of the most powerful negotiating tools is silence."

The power of silence in general is often underrated, but it can be an especially useful tool in a negotiation. Some people are so uncomfortable with silence that they will make concessions simply to avoid it. And sometimes the best response to an unreasonable demand is to just say nothing and stare, letting the other party come to the realization themselves. It takes calm confidence to simply be quiet and let the silence fill the room, which can feel surprisingly intimidating.

"Always listen to your gut, even if you can’t explain it."

Ah, the strange and mysterious sense of intuition that we can't really describe but know when we feel it. Whether it's getting a creepy vibe about a person or a little voice telling you to do or not do something, those "gut instincts" can serve us well. Of course, if we are prone to anxiety, our instincts can sometimes be confused with anxious thoughts, but "go with your gut" is solid advice anyway.

“It doesn’t matter what path you’re on if it’s the wrong mountain.”

Sometimes people trying to find their way end up hitting roadblock after roadblock, which may mean they just haven't found the right path yet or might mean they need an entire overhaul of their life. That might look like switching career paths entirely, rather than trying to find a job in your field that fits. It might mean changing majors in the middle of your studies when you find yourself not enjoying any of your classes. It might mean finding a new community or reevaluating your relationships.

"The harder I work, the luckier I get."

Several sayings line up with this one, like "Luck is the intersection of preparation and opportunity," and "Luck favors the prepared mind." There's a lot to be said for fortune and hard work going hand in hand. If we expect good things to just land in our lap, we will likely be disappointed, but if we move in the direction of things we want to happen and do the work of preparing for good things to come our way, "luck" frequently seems to follow.

Finding a saying that resonates can be really helpful when we're facing a specific challenge in life, especially when we commit it to memory and repeat it often.
