- A large water bottle. I don't drink enough water and this has been game changing for me. I first got a 1 gallon (which I never finished) water bottle but learned that .5 gallon is the right size and I always finish it and often refill. I'd say pick one that meets your needs, but I've tested a number and can highly recommend this one: https://www.amazon.com/gp/product/B094X6N4PG/ It's easy to carry, has a built-in straw and cheap ($20).
- Multiple MacBook chargers. I purchased additional charger for my MacBook Pro at different parts of the house where I sit for long periods of time. Not having to go get my bag and dig out a charger is surprisingly rewarding.
- A second set of AirPods so I have one dedicated for work and one for the gym that I keep in my bag, rather than occasionally forgetting them. It also helps that I can swamp pairs if I have a particularly long day of meetings.
- A robust case for my MacBook Pro. I take my MacBook to and from the office, use it all around the house and have small kids. I've been through multiple cases, including the sleek expensive ones. For me, nothing beats this cheap one I found on Amazon: https://www.amazon.com/gp/product/B083XZ3HP3/
- A rowing machine. The latest Concept 2 is ~$900 which is surprisingly cheap for a great workout I can do at how and relatively quietly while listening to a podcast or watching a game.
- A lapdesk. I use this daily and have multiple around the house wherever I end up sitting. They have fancy ones, but I've found the simple one is the best: just a piece of wood and a pillow: https://www.amazon.com/gp/product/B07K1L3RNK/
