The first place to start in a low-return environment would be to minimize your investment costs.

Every day, I seem to have a discussion with someone regarding strategies for sustaining retirement income in a lower-return world. Investors, particularly retirees, are looking for solutions, and their frustrations are as clear as their request: Can’t someone help? While I can’t fix low interest rates on lower-risk investments (such as high-quality bonds and bond funds), perhaps I can provide some perspective and a solution. As with the old conundrum—is the glass half-full or half-empty?—the answer to the retirement income puzzle is often about perspective.
