-Since 2014, when I started college, I've been on a quest for a lifelong PKM tool. I cherish my life and all my experiences, and I don’t want to forget any of them. When I’m deeply focused on a task, it’s easy to lose sight of other important parts of my life—so I needed a system to help me stay balanced.
-
-Early on, I tried TiddlyWiki several times, but I was initially put off by its save mechanism and markup editing. That changed when I discovered an auto-backup script, which gave me the confidence to fully commit. Over time, I improved the script and eventually transitioned to using TidGi-Desktop and TidGi-Mobile.
-
-Today, my TiddlyWiki holds all my game design ideas and progress logs—it has truly become my second brain. With the help of LLM-powered programming tools, I’ve enhanced it with numerous plugins, allowing me to manage my mind in a more programmable and structured way. As a game developer, TiddlyWiki isn't the core of my professional work; But I've invested so much time because it's fundamentally about upgrading my mind.
-
-Most of my notes are open by default and shared publicly on my homepage as a digital garden.

-''Hi, My name is Mario Pietsch''. Back in 2009 I was ''searching'' for ''a simple presentation tool'' and discovered ~TiddlyWiki Classic, Monkey Pirate ~TiddlyWiki ([[MPTW|https://mptw.tiddlyspot.com/]]) with ~TagglyTagging, Eric Shulman's ~TiddlyTools, Saq Imtiaz's navigation macros, and more. --- ''I was captivated''.
-
-After a deep dive, I combined these elements into my own "Presentation Manager", along [[3 step by step tutorials|https://groups.google.com/g/tiddlywiki/c/qG_tZ1x0MEU/m/-vLA0luMicYJ]] to help others build it. 
-
-Thanks to ''the positive spirit'' of the ~TiddlyWiki community, I am proud to be part of it since 2009.
-
-When Jeremy started developing ~TiddlyWiki 5 on ~GitHub, I joined in—opening [[issue no. 1|https://github.com/TiddlyWiki/TiddlyWiki5/issues/1]] all the way up to 13. For what that’s good ;) Since then, I have submitted nearly 600 pull requests and more than 500 issues, many of which have been merged or resolved.
-
-My ~TiddlyWiki 5 "laboratory" is at https://wikilabs.github.io, and I also share content on my ''~YouTube'' channel: https://www.youtube.com/@pmario

-Have fun!<br>
