Doing both a full time study and a full time job leaves hardly any time to do something else. Consider a life of going to foreign cities and locking yourself up in your hotel room with your study books and hardly have time for family visits.
A quick rundown of your week: 40 hours of work, 40 hours of study, 8 hours of sleep and 2 hours for meals and personal appearance per day makes that 150 of the 168 hours in the week are already spent. In the remaining 18 hours you'll have to travel to and from airports, doing your personal shopping and maintaining relationships...
In my opinion your best choice is bidding for reserve and studying while waiting for a call.
