Living on 58K in salary/per diem? Very simple - dual incomes (preferrably growing dual incomes). Only partially kidding - you need to identify and marry someone who is professional and a money maker. Why marry a poor teacher or a hostie when you could marry a well-to-do barrister or advertising executive? Think about it. These professionals need love too... If you find someone who fits well in terms of chemistry/looks and she is making good, increasing money, then flying becomes more of a hobby and less stressful from a financial perspective.
