Summarize the following:
In order to succeed as a hair stylist, you really need to love this type of work. The job can be demanding and the training can be expensive, but it will all be worth it if you love going to work every day. If you love working with people, expressing your creativity, and paying attention to details, a career as a hair stylist may be perfect for you. Hair stylists need to be extremely personable in order to retain clients. Many people return to the same hair stylist time after time because they enjoy talking with him or her while they get their hair done. You are also likely to get better tips if you can make your clients' experience very enjoyable. If you don't enjoy talking to people or are not very upbeat, this profession may not be right for you. Not everyone will be happy with their haircut. In order to be successful as a hair stylist, you will need to be able to deal with unhappy customers, learn from your mistakes, and not take criticism too personally. Hair stylists spend the majority of their work days on their feet, which can take a toll on the body. If you have problems with your back or knees that make standing for long periods of time difficult, you may want to reconsider becoming a hair stylist. Keep in mind that you will probably need to work evenings and weekends as well, at least when you are just starting out. Before you decide to become a hair stylist, you should understand what your income potential will be and how much the training programs will cost. It is best to do some research on these figures in your area, as salaries and program costs vary dramatically from place to place.  According to the United States Bureau of Labor Statistics, the median annual salary for a hair stylist was $22,770. This does not include tips, so you may be able to earn much more.  Cosmetology programs typically cost somewhere in the neighborhood of $10,000-$20,000. Keep in mind that you might be able to apply for scholarships and financial aid.

Summary:
Have passion. Be a people person. Learn how to take criticism. Be ready for physically demanding work. Crunch the numbers.
