Ever since I found out about Notion, I have used it to organize just about every aspect of my life. I find that it helps with my productivity, as it provides a blank slate for me to build any system I want in a simple and intuitive way. I enjoy building templates and entire workspaces and have done so for my personal life, academics and work environment. As well as this, I have created multiple systems for others through contacts and freelancing work on Fiverr.
If you want to use any of these setups, make sure to duplicate them into your workspace by going into my Template Gallery
