I could actually retire with a million, if not fully retire then I would be pretty close. I would buy a few rental properties and use that as my income - I already have one although it is not paid off yet. I'd still write but I would have no need for a day job, so I guess I would actually semi-retire. Retirement at 35, I like the sounds of that.
It all started with some trips my mum and I took to The Museum of Childhood and Pollock's Toy Museum. My mum saw some old teddy bears and became nostalgic over the ones she used to have. The next thing I know we have a bear delivered in the post. Now we have a sizeable collection.
The first thing I would do, is make sure my family and myself never again have to worry about retirement, because I would find a way to make that money work for us till well into the future. This includes, our home, and health.
Then I would most likely open myself up another vintage / resale shop filled with everything from clothing and accessories, to small collectibles and crafts.
Like Doctor Evil learned, $1 Million Dollars went a really long way in the 1960's, but without proper planning, not so much in today's time.
