While being quarantined in my house there is not much that you can do. The only boundaries are your house, you cant go anywhere else to do anything unless get essential stuff or else you will be at risk. When you have only a small space to do things you find things that you can to.
Behind My house i have a small shed that I keep all of my thing that I use for fishing. It is not very neat or clean in there so I decided to clean it up and add some things that would make it more neat.
I took some old wood that we had from previous year building a hockey rink in the winter and I cut some up to make shelves for all of the bikes where I kept my lures. I also nailed some nails into the wall so that I could hang my fishing rods horizontally. I put a small table that was abandoned in our garage and I put some tools and other things. And then lastly I took and old broken rod and nailed it to the wall to make holders for my fishing line.
Even though it does not seem like it, there is many things to do that can make you occupied throughout the day, it is just a matter of finding them.
