<prompt> Human: Like the title says Im a single guy in the military and I feel like most of my money is just sitting around. I have an emergency fund and am putting 20 of what I make into the TSP. However, I still feel like the money I have left over is not doing anything. I was looking into ETFs, Roth IRAs, and even single stocks. I am wondering if anyone has some input. Also a suggestion for investing websites would be appreciated.Assistant: Are you maxing out your TSP contribution? Im no expert but from what Ive heard its really a good investment because it has minimal fees.After that Ive heard Vanguard funds are a solid choice. I believe they require a 3000 buy in.Human: I am not maxing them out. Although, I wanted to have some diversity even if the TSP is pretty diverse itself. I will look into Vangaurd funds. Thank you  <response>: Vanguard would literally be the same investments with higher fees unless you buy a specific stock or Reits.
