I'll tell you my reasons.
Ever since I met my spouse, he has talked about early retirement and financial freedom. Freedom 45. Time. Time and financial means to visit family, travel the world, and endorse humanitarian and charity programs. Not that he had a plan figured out (that involved me, anyways), but that has always been the goal. That is still our goal.
So we set about trying to figure out how to get there. He once told me that if he never got married and remained living a 'university student lifestyle' with roomates at a rental house of $300/mo/per person, he could have saved up enough cash by age 35 to retire and live off the interest. He even has a spreadsheet detailing the numbers. But we got married, and I guess that sort of ruined that plan. :D I've looked into countless work-from-home opportunities to try to find a side job that would get us ahead, and keep us ahead while I become a stay-at-home mom with our future kids. We actually consented to meet with people from a few different network marketing companies, thinking that might be my side-job. He has researched endless investment potentials, including stocks, bonds, ETF's, REITs, investments with dividends or not, etc etc. We dabbled in some mutual funds, some ETFs, but never quite felt like we were going anywhere fast. Turtle speed would have been faster.
