Dealing with a loan can be done in a few different ways. It normally depends on your income, as well as your planning strategies and future expectations. Aggressive payment plans have always represented an interesting solution, but just like any other repayment idea, this one needs careful consideration.
A lot of people with a good income feel tempted to just give up every single coin for their debts. They make more than what they need, so they choose to just get over the debt faster. If accepted, this idea will clearly lower the interest rate in the long run. Besides, they will lose this pressure a lot faster. After all, the quicker you get rid of a loan, the better. However, there is also the possibility to actually become way poorer overtime, especially if they overlook the chance to save some money instead. Keep in mind that just because you have paid more money before, it does not necessarily mean that the bank will give you a break later on if you somehow lose your job or face an emergency.
At the same time, remember that personal savings provide a little flexibility, while the money gone to your lender is practically gone for good.
