Me. But I had a number of major expenses (engagement ring, large wedding, attended dozens of weddings, bought house, furnished house, bought cheap/used car, finished paying off my student loans, finished paying off husband's credit card debt, also had no income for a few months as I transitioned into a new career) and felt obligated to put 2.5 years worth of our joint living expenses into a high yield savings account since husband doesn't earn an income and my income, while substantial, is highly unstable and largely dependent on a good economy. If there's a recession, I doubt I'll make anything close to what I'm currently making. I've always maxed out my 401k, so I haven't *completely* missed out, but I only now feel stable/secure enough to begin aggressively investing post-tax money into stocks. No regrets though - I value peace of mind over completely maximizing my net worth. But anyway, I'm pretty pumped to finally start pumping money into the market - better (a few years) late than never!
