It doesn't need to be guaranteed, it just needs to be better expected value, with a volatility you're willing to accept. Risk, like debt, is not always a bad thing, as long as you're informed and understanding of it. As Daniel Kahneman said in 'Thinking, Fast and Slow', people ought to take more opportunities with risky outcomes with positive expected values - some you will lose, but over your life, taking a large number of these risks will result in a positive outcome. (Obviously, only take risks where the negative outcome is one you can get through, i.e. it won't kill you, or leave you completely penniless etc.)
