Quoted from darcangeloel:

This is exactly right. I know it's not a popular idea but man buy and hold still works. Keep and eye on it but for the most part just leave it alone. I personally just buy a leveraged S & P 500 Fund like SSO or SPY, I personally feel safe as I feel like I'm investing in the biggest companies as a whole across several sectors so unless the entire economy decides to tank and stay tanked forever or if the fund managers lose their minds it won't be an issue. So far its worked out pretty well but again the key is for the most part is to just not look? Like when I bought shares of SSO in 2012 around $25 a share I figured man it would be cool if it got up to $35, it is currently at 103 just 5 years later. Meh thats cool hopefully it will keep up in the mean time I will leave it alone (Well for many many years actually hahaha).
