Hmm interesting question.. I think it's always a work in progress for me. When I entered in the workforce a decade ago, most of my income is from my work. Fast forward to my current self, like most people who have worked for more than a decade, one likely would have accumulated some savings/assets, which are generating some income, be it interest, coupons, dividends or capital gains. Based on this trend, this "investment income" should "add" more and more significantly to our work income.
Are you getting more from your investments? Is it enough? As you know, it compounds, so if able to add a little more each month for the next couple years, it might have a massive effect in two decades from now.
Yeah it's getting more and more as the base grows from my wage as well as the compounded returns each year, it's not significant relative to my wage yet, hopefully, one day I will reach my personal goal.
