My Long-Term Investment Portfolio… so far

Recently, I acquired (roughly) $20,000. I immediately set my eyes for the long run. I wanted to invest it all, and I don't plan on selling anything for the next 5 years, hopefully 10. Here is what I have invested so far:

SWTSX – 12.5%

VIGAX – 12.5%

QQQ – 10%

VOOV – 10%

VTI – 10%

I have roughly $9,000 remaining. No idea where to go from here. Tell me where I went wrong… (jokes aside, any feedback would be helpful)
