Work.
If you are a working, full-time, professional dancer these things will be true about your life. You will wake up sore. You will dance all day. You will go to bed sore. You will work seven days a week. You will take class, teach class, and be up to your elbows in projects. You will never stop having to take class. You will take on projects that go well. You will take on projects that go terribly awry. You will always worry that there will not be another project to take on. You will worry about your weight. You will memorize everything you do. You will get on stage and forget some of what you memorized. You will keep dancing anyway. You will never get sick enough to have to stay in bed. When you do get sick enough to not get out of bed, you will get out of bed. You will be alternately told that you are talented and gifted and that you have no talents or gifts. You will invest enormous amounts of time and money to train in what you do. You will get paid for little of what you do. People will tell you that it is okay that you do not get paid because you love what you do. People will also tell you that you are not really working because you love what you do. You will love what you do. You will still be working.
