I have been personally curating these tools for some time in my notes and also used many of them in 2019 to try and become better
I even used some extreme steps like completely giving up on smartphones and used a Nokia 3300 feature phone for 5 months! :D The toolkit is a curated list of all the tools I used, and the practices and tips that worked for me.
2019 was a great year for me on becoming more productive and hope this helps others too!
