First, determine what you'll need to contribute to reach your retirement goal. You want a nest egg that can annually deliver between 70 to 90 percent of your pretax, pre-retirement salary. How much will you need to contribute to reach that goal? More importantly, how will you ensure those contributions are made?
Next, you need to create a budget of your recurring expenses and include your savings contributions as a monthly expense. A budget will also clearly show you where your money's going and should also provide some insight into what debts should be dealt with first. Now that a plan's in place, you're going to need to change your mindset in order to stick to it.
