I hold two jobs as a lifeguard. One is at a summer-only pool and the other is year-round at an indoor pool. I worked throughout the entire school year last year and it was manageable. However, this year I am taking four AP classes and picked for a leadership position in an activity that requires a large time commitment for the first part of the school year. Also I will be participating in and practicing for a musical group that will take even more time. Should I keep this job?
