$1,000,000 is roughly £745,000.
I would invest in two properties of circa £200,000 each and rent them out, giving me a regular income. One would be in Scotland, where I would like to retire eventually, the other can be wherever the market is on the up and it would be sold if either of my parents became ill, which I daresay is inevitable eventually.
I'd spend circa £145,000 on a new narrowboat to replace my current one (plus whatever I can sell this one for).
I'd set aside £100,000 for training courses, and take whatever I fancied doing. Either as possible employment, or for pure education, or arts and crafts / DIY amusement, or to have more skills to offer as a volunteer. Depending on how things went, some of this could also be used to start up hobby businesses.
I would spend my time travelling around doing a variety of jobs, both paid and voluntary.
With the remaining £100,000 I'd buy a classic car and a miniature steam locomotive, with enough set aside for their storage, upkeep and use.
