This one was particularly interesting as this is something I am really starting to worry about since I am almost 40. I have been using a 401K of some type since my early 20's but never really paced what I was supposed to be putting in. Now I am trying to make up for lost time.
The part I found the most interesting was dealing with the fact that we should not be investing in mutual funds but rather index funds. This is something I need to talk to my advisor about (I have new questions for him as well especially regarding fiduciary) and what is opinions on the matter are.
