Some high-paid jobs that are enjoyable require extensive training or education before it is possible to be hired. Airplane pilots are highly paid, but also highly skilled. Many musicians complete rigorous training in college or in specialized academies before entering the field. Culinary artists, such as chefs and sommeliers, can make excellent salaries, but the training for those fields is demanding. Personal trainers, hairstylists, makeup artists and personal assistants can also make high salaries once they achieve a certain level in their careers. They may obtain training before entering the field, but certainly must work a number of years in the field before hoping to earn high salaries. Editors can also earn good salaries, but it is almost always required that they work up through the ranks and entry-level publishing jobs are very low-paid. In many cases, interns are required to work without pay to gain experience.
