The common problem that people may encounter when trying to achieve an education for a career is the cost. The career that comes with the education must pay well enough to be able to pay off the schooling. The benefits of schooling can differ greatly depending on the degree (or certification) obtained, the programs the school may offer, and the ranking of the school. Sometimes, colleges provide students more with just education to prepare for careers. It is not uncommon for colleges to provide pathways and support straight into the workforce the students may desire. 
Overall, this is an excellent start to a compelling essay. Keep in mind that although the committee allows you to write up to five pages, three double-spaced pages is usually adequate. Feel free to add more detail, but make sure your text is concise and transparent. You might consider "writing" ideas and then "rewriting" them. Too often, authors put ideas onto the page, but do not render those ideas compellingly. Giving your sentences a bit of extra effort, and giving your experiences a bit of extra reflection, will result in a persuasive essay that compliments your accomplishments and character.
