there are few dynamics need to consider before starting diversification : 1. Skill 2. money 3. time 4. scalability of the second source of income . Diversification if done right , is a brilliant way and stats are in line with it. Most of us dont know how to diversify , we do little or no study and we are kind of complacent . Millionaires are rather opposite , so the diversification works for them and for us not so well. I think diversification is subjective skill . Thanks for the content
