I'm considering this too but I might just wait till the beginning of 2022 hoping thats when the entire world opens up. I can't break my lease before November, so that helps me stay at my job. So many ideas though for 2022,

1. Cycle Eurovelo 6

2. Drive through the Pan American Highway

3. Learn different things at different places, Muay Thai in Thailand, surfing in Bali, Kali in the Philipines

4. Just travel doing nothing for a few months and then try 12 month 12 startups or something.
