I'm not in quarantine, but I broke my foot so I'll call it the same thing since I'm stuck at home for 4 months (only 2 more months to go!)

I decided to use this as an opportunity to learn and grow, just like you

-Read 20 books (16 since the start of January - including taking notes) on a variety of topics - finance, investing, self-help, career development, science, philosophy etc, as well listened to many podcasts and productive YouTube videos

-Studied toward a new certification for my line of work (and set to receive a pay bump by the time I return)

-Created a budget using YNAB (You Need A Budget) and organised my finances. I now have a financial plan and looked into retirement planning as well.

-Made my initial move into investing in ETFs, and am doing some paper trading now on a few stocks I have my eye on

-Read and understood all I need to know about my various insurance policies, super, medicare and other important things I just had a vague idea about previously

-De-cluttered my phone, laptop, home office and home

-Begun learning Spanish and Russian on the DuoLingo app

-Bought a guitar and began learning how to play it from JustinGuitar

-Set up home automation - sensors, cameras, garage, wall plugs etc (so convenient not having to get up with a broken foot!)

-Begun tracking my mood and habits in the Mood Tracker app

Switched from doing Tactical Barbell in my training to doing a new bro-split bodybuilding protocol just for fun
-
-I've also bought a lockpicking set and am waiting for that to arrive so I can learn how to pick locks

And then I've continued my previous practices:

-Cold showers

-Meditation

-Practicing Mindfulness and Gratitude

-Journalling

-Study and implement Stoicism and Buddhist practices into my everyday life

Then on top of all this I still fucked around and did some lazy shit like

-Video games

-Binge watched Attack on Titan, the whole MCU line-up, Friends, Brooklyn 99 and other content from AnimeLab, Netflix, Disney Plus etc

-Reddit

-And other mindless stuff because I think it's important to have that too (in moderation)
