a civilian mentor can help you navigate the unfamiliar terrain and language of the civilian job market. While you were serving, a civilian mentor was working his/her way up the corporate ladder or building a business. They have first hand experience with the challenges you are just becoming aware of.
the decision to join the military is one with pros and cons. However, a career in the service carries with it a unique set of responsibilities. While I still recommend a career in the military to young people, I do so with the caveat that each person should fully understand the unique nature of the military before they join.
There are other routes, such as finding an agency to look over your resume or write it for you. While many will charge you for the service, there are a few, like Operation MCP (Make Careers Possible), who will help a veteran work on a resume for free. If you have never put a resume together before, they can assist you in translating your military skills into something a civilian employer will better understand. In the end, your resume will get better, but it will still need to be tailored to the position you want to apply for, so be prepared to make changes.
