I didn't draw early because I couldn't believe how much they were going to cut my check for the rest of life for starting say 3 months early. I totally qualified and now you can earn anything you want after you qualify.
One thing you may not be aware of is you can have federal taxes taken out of your social security check if you are in the group that gets 85% of your benefits taxed. Depending upon your situation you can have 7, 15 or 25 percent taken out. And there is a way that you can access your account at social security and change these amounts as you wish. I have a temporary password but I haven't set up the account yet there.
Due to the economy my hours at work were cut to 20 per week and so this is just going to make up for that loss. I look at it as easing into retirement!
