I love retirement. After retiring at 50 in 1998, and immediately moving to a rural area and building our dream house (a bad financial decision as we discovered four years later when we moved back to mid-city urban), we continued our careful spending ways that made ER possible.
But now that we've started SS benefits, and our withdrawal rate hovering around 2% vs. 4+% before SS, I've found myself much more comfortable in spending more money, like in recent months for nice tablet computers and the most expensive car we've ever bought (Ford C-Max Energi).
So based on my experience I recommend being careful about rash decisions early in retirement, but enjoy the experience by using your assets appropriately to live the best you can.
