I'm probably dong my dream job now, but only because I'm in my 50's and not too fussed about socialising : I look after dogs in my home, when people go on holiday or need doggie day care.
Most days I have 6-8 dogs here. The first few years were very hard, because a lot of the dogs were really badly behaved (chewing, excessive barking, crying in the night, pooing indoors etc), which is way more stressful than it sounds!
But after a few years of weeding those ones out, I'm left with a brilliant bunch of about 80 dogs, who are absolute super stars.
My day starts at 6.30am, when I let out any boarding dogs in to the garden for a pee. My first dog arrives at 7am for day care, and then another few turn up around 8.30am. We go for a nice walk around 10am, and then they play or sleep until about 4pm when we start to think about dinner and the next walkies.
So I really don't have much to do between 11am and 4pm, apart from letting them out frequently, having cuddles etc.
It pays my bills and then some. I'm my own boss. I don't have targets. There are no overheads. I take my holidays whenever I choose (pick around my DH's dates off work).
In my opinion, if you are in a job you don't like, it's very hard to pack that in and "try" something else, because that means making yourself unemployed and losing a salary, based on a whim!
In my case, I was working for Bank and was offered VR. The pay out was good, so I took it, and then tried my hand at this, by advertising on Gumtree and Facebook, and leafleting the area. It actually didn't take long to build up a good client base, and then a few years in, I stopped advertising and didn't take on any new dogs.
About every 3 years, I do open the doors to new dogs again, because of natural wastage - dogs die, people move house etc, it takes me a few months to have enough rotating dogs again, and then I pull up the drawbridge again.
It's a bit solitary, compared to being in an office, but I have great customers who I have a laugh with, and I do not miss the daily commute and having a boss to answer to!
