For me, life doesn’t amount to only work and study. Hobbies are an incredibly freeing method of expression: you create the vision, the purpose. You choose a direction, and you follow through (or not). I’ve taken to approaching personal projects as my playground, going where my curiosity takes me and having fun in the process.
If you enjoy reading books, you might want to check out my bookshelf. For software, you can check out my personal software projects.
