I learned this while i was still in college. I was working part-time and i would think about the things i wanted to buy and my expenditure throughout the month. In this time, i thought about keeping some money on the side to pay my student loans for when the time comes. Since i was already saving some money for future expenses, i created another savings account to save for my student loan expenses and so i started putting in little sums of money into the loan account and by the time i was done with school i was able to pay off about half my loans.
It really worked well for me and i hope it does the same for you.
