Have you ever washed a dog? I think I have "professional" dog washer in my background as I used to volunteer for this with the local humane society in the summertime. The lesson learned here was
Washing A Dog Gives YOU The Bath.
It is a good lesson in moving forward without fear in many things we attempt in life. It really is how we grow. We have to learn to "expect the unexpected." You might get wet yourself along the way of accomplishing your mission. Setbacks, surprises (both unpleasant and pleasant), hating what you are doing, loving what you are doing, you just never know.
The most joy I have found in doing things you have never done before is the people you meet along the way. I think any pain encountered is well worth it just to meet new folk and get a glimpse of life from their eyes.
People and relationships are so much of what life is all about.
So don't fear trying new things and saying to others that today you're going out there and wash a few dogs. When you look back on it when your hair is wet, your pants are soaked, and you have soap bubbles in your face, it really was a pretty fun day.
