You can start with a day job as a member of a small crew on a yacht or superyacht, depending on which you can get first. Although the work you will be assigned to might look mundane, the attitude you bring forward when working is what will set you apart for a more permanent role in the nearest future. That is not to say the right attitude is all you need if you really want to get this job; you have to consider mastering some skills like your bartending skills or your proficiency in providing silver service before considering an application.
