6 ways to screw up your retirement plan
Mistake No. 1: Opting out
One of the biggest mistakes is to decide not to participate, said Robert Gordon, senior financial adviser at Investor Solutions.
"As the saying goes, 'you've got to be in it to win it,'" he said.
Definitely don't opt out if your company offers automatic enrollment. It will also automatically select an investment option for you -- often a target-date fund. Once you're in the plan, take time to acquaint yourself with all its investment options so you can determine if the preselected fund is the best choice or if there's one that better meets your goals.
