I think at your age it's good to have a deep discussion with spouse about what your true goals are. Retire early? At 65? Enjoy all the niceties of cars, bigger house along the way? Most here have at some point decided to live way below our means to reach some early retirement goal. For me, I sort of fell into it at 30 when I had a job change that added about 35% of salary, no move or other changes. We made a commitment to put the majority of that into a 457, then limited to $7,500. It increased over the years, when I could I maxed once 55, and also maxed a 401k.
Through those years I followed it, learned a lot including getting burned on tech at the turn of the century. Come here, read books on it, get comfortable with what your goals are and stick to it. I think a Roth is excellent, started those several years ago for DW and me. This stuff isn't really all that difficult to understand, just need to develop a plan and stick to it. The hardest part is to separate the emotion from the dips and highs. That's where assessing your ability to withstand those frights (risk tolerance) is a good place to start in developing your asset allocation. Anyway, good luck and welcome!
