Hello, Mustachians! I am going to put in the maximum contribution ($5,500) in a Roth IRA with Vanguard and would like some help choosing the fund(s). I am 30 years old and plan on retiring in 15 years or so. I will be opening up the account in the next few days and I have three different strategies I am toiling over. They are as follows:

- Target Retirement 2035 Fund (VTTHX)

- LifeStrategy Growth Fund (VASGX) (this is an 80/20 allocation)

- Three-fund portfolio (VTSMX, VGTSX, VBMFX) (Boglehead strategy)

Any suggestions on these three options or any other fund(s) I should go with? Any help is appreciated!
