That depends what you call a “good” lifestyle. Could I rent yachts and get bottle service every weekend living off my passive income? No way. Could I travel 10–15 weeks a year and live in central Tel Aviv with money to spare? Definitely. I was able to earn low 6 figures completely passively. But if you want to make boatloads of money, and step up to the 7-figure territory, then yes, you’re going to need a combination. If, however, you want time to pursue your passions and have a moderate amount of fun, you can definitely sustain yourself with passive income.
6) Always Remember That Everything Is Relative. The best way to determine worthwhile passive income streams is by comparing the likely return (IRR) with the current risk-free rate of return. If I round up, the 10 year bond yield is at 3%. Any new venture should thoroughly beat 3% otherwise you are wasting your efforts since you can earn 3% doing nothing.

4) Treat Passive Income Like A Game. The only real way to begin your multiple passive income journey is when you are making active income. The initial funding has to come from somewhere. Hence, treat passive income as a game that has various levels. If you fail to achieve one level, it’s not the end of the world since you still have active income and can restart. Furthermore, a game is meant to be played with integrity. Using shortcuts (non passive income streams), someone else’s income as a supplement (spouse), or one-offs (capital gains) does not count. The primary purpose of any game is to bring enjoyment to the player and beat the boss.
