Ever since I was a little kid, my Dad had given me multiple pieces of advice.
It's what Dad's do, they raise and educate their kids. The thing that has always stuck in my head, ever since I was little, was a concept my Dad would always say. No matter what we were doing or where we were at, he would tell me, "You always leave a place better than when you got there."
This was applicable to campsites during our scouting days, someone else's house we were visiting, even public restrooms. When I was younger, and even now as an adult, I will see Dad wipe the water from the sink in a fist of paper towels and throw everything away. I had watched him do this all my young life. And now I do the same thing.
Whenever I am out, I stack the plates for the waiter to take away. I wipe the water up in public restrooms. When I go to the park or anywhere with nature, I pick up litter and throw it away. These small actions can go a long way. It's spreading good vibes and just a simple act of kindness can really alter someone's day.
I challenge you to start this. Start leaving places better than when you found them. You'll feel good as you leave and you could really improve someone else's night. It's all about simple helpful things.
