What is a good thesis statement for why is choosing a career is very difficult?

Choosing a career is very difficult.

• Given the current state of the job market, it is no longer a question of which career one shpould choose, but rather a question of whether one will find employment at all. (to begin an essay on unemployment)
• Our choice of career may be influenced by a number of factors, for example, our preferred town of residence, our skills and aptitudes, and whether or not we wish to have a family. (in an expository essay on the factors that can determine our choice of career)
• Daunting though the task of finding one's ideal profession may be, it is made easier by institutions such as careers advisory services, websites with job listings and work experience and job shadowing schemes. (to begin an expository essay on the services available to the job hunter)
