@Chris - You are one of the few people who have ever asked me this! Wow and thanks for asking!
In 1996, one year after I started my own business and was in a debt for my car, my house and the business loans, I read YMOYL and it made me think that I could be FI. The money would have to come from the sale of the business. At that time I was working the business about 6 hours each day while working for a colleague about 4 hours each day. I wasn't being paid much, probably about $23K from my boss and the business wasn't paying me anything, so that I could pay down my start up costs. Shortly after I read the book and started tracking expenses it did make sense for me to move to my own business full time (12-16 hours each day) and work at building it up and maxing out my income. I figured I was making $11/hr when I did my initial hourly wage (what I traded for my finite hrs on earth according to YMOYL). But my business did start to grow with all the time I was putting in. I did my own work, much of my own billing and accounting, as well as payroll and everything else. I didn't take a day off for the first year and worked 6 or 7 days each week (the business was closed on Sundays, but sometimes something needed doing anyways). After I moved over to my own place I took off Tues and Sat afternoons.
My business starting doing well and I started a SEP-IRA account and I could often put away $2-3K each month. I paid off my morgage and car loan, paid off some business loans while taking on lines of credit against my paid off house (interest rates were cheaper that way). I also borrowed from the bank of DAD and was proud to pay my parents 10% on the loan they made to my business even though my Dad said that he would give me leeway with payments. Ha, I never needed to and paid his loan in 3 years. So, after a couple of years running my business with very little social life and not much personal time, I did meet my current DH. We took a weekend away and he took me to the area where we live now. He was sick and tired of always being on call and wanted to move to this new area to live and asked me to marry him and move there. I did think that my business was salable, but it actually took me a stressful 18 months to sell it. At first, I wanted to leave the area, but didn't want to leave my business, my staff and my clients and I think that because my heart wasn't totally in it, that energetically or vibrationally, I held up the sale of the business.
So, I sold my business for $400K in 2001 (5 years, 3 months later) and held a note on about it for about $100K. This put me at my crossover point of 6% of $400K or $24K, but I actually had a little more money than that and I had a paid off house that I rented out for income after we moved.
I did get married and that changed the financial plans a bit. If there is interest, I can tell you more about that some other time. Like you said there wasn't support from DH to get to that point, so I managed to make a deal with him and keep finances someone mingled and somewhat separate.
@Jacob - I would be honored to write a guest post for you. I just need to figure out exactly what I do with all my time!!!! Let me know the details of what you want and I will cook something up.
