1) Caterpillars can't swim. Or even float for long. I proved this beyond a shadow of doubt when I was 5, by floating one in a bathroom cup for two days. After noting that it sank to the bottom and no amount of poking could revive it, I flushed the remains and replaced the (unwashed) cup back on the counter for my sister to use. Experiments are useful for satisfying one's natural curiosity.
2) It is not necessary to tell others of your experimental failures (or successes) -- especially when they mention the "funny taste" in the bathroom cup. Sometimes it's best to keep those secrets to yourself.
3) Electricity is a very tricky thing--when you stick a plug in an outlet with one prong in the outlet and one in the wall, it short circuits the power to the whole house, thus prompting an expedition by flashlight to the basement panel box. Note, this experiment could also result in short circuiting YOU, so don't try this at home! See what I mean? Childhood is fraught with danger!
4) When you rescue small furry animals from pain and possible death, comfort them and feed them, they are devoted to you for life. Over the course of my long, illustrious career as a rescuer, I saved 2 dogs, an abandoned kitten, 7 shelter cats, a duckling, a dozen baby birds, untold numbers of geckos, and many other assorted critters (and still counting!) I have found that rescuing critters is more rewarding than trying to rescue people, generally speaking. There might be some exceptions to this rule. I'll let you know.
5) When you are flying solo (i.e. without training wheels on your bike) for the first time, know that you can do it even when your Dad lets go. I didn't believe this and crashed the moment I realized he wasn't running along beside me anymore. Self confidence is crucial, in bicycle riding and life. As soon as you let doubt and fear creep in -- you fall. It always helps to have a guiding hand of love to keep you going until you realize you can fly on your own. Trust the love. Trust yourself, too. Love will always pick you up after you fall, dust you off, dry your tears, and praise you for your excellent effort.
6) Mothers can't actually tell if you are fibbing by looking into your eyes. About most other things, however, they are usually right. I also noticed that my mother got increasingly smarter as I got older. Interesting how that happens. I find myself remembering and speaking her words of wisdom now. They are still relevant and true.
7) The external scars of childhood will usually heal on their own with time. Some of the more spectacular ones remain as badges of courage and honor, and good conversation starters. The internal scars may need some extra help to heal. Ask for help with this -- from friends, family, God, Mother Nature. Even when life hurts, try to keep your heart open to others and keep the circle of giving and receiving love going round. Be adventurous! Dance, sing, play, and love fully in each moment, with the openness and joy of a trusting child. Decide in advance that the Universe is a good, kind, happy place. And so be it, so it is! Remember Abraham Lincoln's sage advice: "Whether you think you can or think you can't, you are right!"
