Mingling with people, hurting them, getting hurt by them. That’s how you learn about people and about yourself.
Imagine that you are standing in the middle of a pile of dirty laundry. It's everywhere you look. What's even worse, you don't have a washing machine and everything has to be washed by hand! You don't even know where to start.
When you get anxious about the future, it is better not to think about it. The more you think about it the more anxious you’ll get. Of course it’s important to think about what lies ahead, too, but if you only look at what’s down the road, you’ll get tangled by the “laundry” by your feet and fall, won’t you? You see, it’s also important to think about what you can do now. What you can do today, and if you keep washing things one at a time, you’ll be done before you know it.
