Actually, I picked up a few new hobbies, dropped the planned hobby of travelling and grew totally disinterested in the hobby of writing software for myself instead of as a profession.
I had expected to travel the world and had my bucket list of locations. So, I did a couple of trips in the first 11 months of FIRE. The second was to Mexico where I fell sick with GBS. I went through a one-month hospital stay and months of learning to walk and struggling with double vision. My neurologist does not want me to travel, especially to locations where I might fall sick as my GBS could be retriggered, effectively killing all of my traveling plans.
During my recuperation, I got interested in the birds outside my window (nothing else to do since I could not read or watch TV). I ended up ordering a bird feeder from Amazon and relocating a bath near it. I ended up with endless entertainment and a desire to learn more about birds. I found a great community of birders on this forum who gave great advice and guidance (Thanks
@wenchsenior and
@Parizade).
So, now I got interested in making sure I had a great bird environment in my back yard. When the local Audobon had a native plant sale, I ended up buying a couple of milkweed plants and I suddenly had Monarch butterflies visiting and a whole crop of Monarch caterpillars. I decided that I am now going to make sure that one part of my garden is going to be a butterfly, insect and hummingbird garden. I have spent the last couple of months planning out my butterfly/insect/hummingbird garden. I cannot wait till spring when I can start implementing it.
I pulled out my old DSLR and tried taking pictures of the birds and butterflies. I used to be a poor photographer who mostly used the automatic mode and did not know the basics of composition or the technical aspects of photography. So, the University of YouTube has been a great educator. I abandoned the kit-lens and splurged for a couple more lenses, a telephoto, and a prime (cheap) lenses. And a tripod. I have started shooting in RAW instead of jpeg and am using the free RawTherapee to process my photos (still a work in progress).
TLDR; Lost the planned hobby of traveling and found 3 new hobbies, birding, butterfly gardening and photography.
