You don't say what your major is, but your plate may be too overly full. I say that as one who worked 2-3 part-time jobs while carrying a full load of in person classes and being actively involved in a number of extra curricular activities. As a journalism major, I've always maintained that I learned more outside the classroom than in -- at that is only partly hyperbole -- but my grades suffered, including being on academic probation for a semester. If your major is science related, it is even a bigger challenge. Is the book club really important at this stage in your life, or something that can be postponed? Exercise is important for health, energy, and mind clearing, but do you need a full-blown personal training program at this time?
