Oh boy. A ton has changed over the past decade for me. Ten years ago, I was in grad school and living in my parents basement. I had some small internship income and basically no expenses. My spreadsheet for Jan 2016 shows I spent $160 that month and earned $230. I'd started investing the previous year and had a net worth of roughly $40k.

Now I'm married with dual tech income, have a dog, own my house. My spending for last month was roughly $3000. I have expensive hobbies, go on big exotic trips once a year, spoil my dog endlessly,etc. My life is so much fuller than it was back then. My net worth nowadays has crossed the 2 commas club.
