New projects can make my soul young again. Do you feel the same way?

My junior colleagues and I are working on writing an article to be published in a scientific journal. This is not an office job. It is our initiative to disseminate government data and information so that scientists can read it. We even fund the publication costs together.
I used to do scientific writing activities, but I left them for years. Now, I’ve started them again with my juniors, and thank God for the excitement we experienced. This activity really makes me feel young again. My junior’s spirit seems to flow through me.
Below is another project.
I am currently working to build an apartment for myself near campus. With the help of an interior designer, I have designed the space according to my personal taste. It truly feels like a home that I have created myself. The apartment features a mini balcony, a workspace, and a small kitchen. Although it’s only one bedroom, it’s compact and efficient. I could see myself spending two or three days a week here, reading and developing my writing. Constructing a building from zero to one will be an exciting experience.
Friends, what personal projects (outside of earning a living for your family) are you working on right now?
Can the project divert boredom from your monotonous life?
