Take it or leave it, diversification of income to me is very important and have once read a content on a platform some years ago as regards what it takes and he help you get when your income is not based on one way alone.
I once brought up with the understanding that No One Made It Through Salary,which means most successful or ruch people this days have other source of income to meet up their day to day needs.
I strongly stand on my words that having different means of income is a way forward in life
