I have no debts, mortgage, children, or familial obligations.  I work in Information Technology and I'm also a full-time student majoring in the same field.  I receive free healthcare and education as part of my veteran's benefits.  My current rental lease ends March 6th, and I will be moving to a more affordable home with roommates to split the costs of living.  I also plan on selling my car which I (foolishly) bought new in 2011. 

I save and invest about 80% of my income, and I've been able to build up a decent sized nest egg over the years (especially after my income more than doubled last year).  Now that I feel I have enough saved and enough stability in my personal and professional life, that it's time to start letting my money work more for me, stay ahead of inflation, and grow.  I had been very risk-averse for many years when it came to investing, and as such, never entered the markets until last year.  I'd like to optimize my investments as much as possible in a diversified, low-cost, tax efficient, and fairly simple plan for both my retirement and brokerage accounts.  I would also like to get my money out of CD's and into something that has a much higher earning potential, like Vanguard index funds, although I'm not sure what allocation I should go toward.  Also, I was hoping to get some input on my Roth IRA and 401(k) allocations and how I can improve them.

Next January, my girlfriend will be moving in with me.  I would like to purchase a home in the next 6 years, as well as to retire from my day job (if possible).  We plan on moving to her home country where the cost of living is significantly cheaper than here in the greater Seattle area.  Considering these factors, I'm not sure if I should be contributing more into my 401(k) or maximizing it up to the annual contribution limits. 

I would welcome and appreciate any suggestions, advice, or feedback at all.  I'm excited to finally participate in this incredible community!  Thanks for your time.
