Two decades in particular, the 1970s. and the 2010s
In the 70s I Graduated from Uni with a good degree, met Caroline and got married, had a great job, bought our first house, amazing music,
In the 2010s we sold the business I'd set up with a US partner in 2002, paid off the Mortgage, bought the Roadster, both kids in good secure jobs and I was employed by the people who bought the business, so stuffed the pension SIPP, then retired.
There was a lot of good stuff in every decade, but those two stand out.
