Your Retirement Savings

I took voluntary redundancy from my office job during the pandemic and used the money to set myself up as a gardener. I don't earn very much now and my wife doesn't work due to her MS but we just about scrape by. I'm doing a job that I enjoy, i listen to music or birdsong all day long, I'm my own boss, and i spend most of the day away from a desk. i feel like i'm mostly having a positive effect on the environment (i'm steathily turning all my clients' gardens into mini nature reserves, just sneaking in little things here and there; i did get stung by bumblebees today though when i strimmed the grass too close to their nest, i tried to be their ally but they've turned against me). I don't have any real savings but as long as I can hang on to my health and don't injure myself falling off a ladder or something daft, then once I reach a certain age and our kids have moved on, I hope I'll end up just working mornings, pottering around people's gardens as a doddery old man, trying to be useful. At least it'll get me out of the house and keep me active. Things that might scupper this plan: my wife's health significantly declining so that she needs caring for; also the cost of running a crappy old van is killing me at the moment, and any surplus I currently make is used to keep that heap of shit going :(
