Nassim Taleb has advice to follow something called "the barbell approach" where 90% of your money is super safe (all stock market index funds/t-bonds/etc.) and 10% of your money is in some super speculative asset. I don't think it's bad advice if you're willing to commit to the speculative asset over a long time horizon and you don't have unrealistic expectations.
