I've been thinking about all of the things that I've learned the hard way. Some things build character, but others are just poor, poor choices. This list is of those:
1. It is not cute, let me repeat, not cute when you teach your English bulldog to jump in the bathtub. He will turn your shower time into a game of porcelain roller derby. Plus, forget about it ever being clean again, perpetual muddy paw prints.
2. Don't use a sewing machine late at night and/or when you are very tired. You'll end up with a sewing machine needle in your finger or something worse.
3. Riding your bicycle to a bar might seem like a smart way of not requiring a designated driver/cab, but it is not. Even though I've sustained many cuts/bruises/road rash, I still do not heed my own advice.
4. Put oil in your engine. So simple, yet something I ended up learning the hard way at 17. Oh, and as an extra - if your engine is steaming, do not pick up something that just fell out of it with your bare hands.
