- I bought a Fitbit and aim for 10k+ steps a day
- I rarely make coffee at home in the mornings, instead going to a local coffee shop to purchase one
- I try to go out for lunch every other day (normally just somewhere quick and cheap)
- I meet a friend for dinner, go to a meetup, or just go to the pub 1 or 2 nights a week
- Play a sport (I play Squash) which gets you out of the house and exercising
These have helped me a lot although I do still fall into bad habits. In 2017 I worked from home for 6 months and almost exclusively ate takeaway, played video games in the evening, and rarely went outside during the working week. My mental health really suffered during that time and it took a while to get back out of it!
Note I wouldn't want her job for anything. She has to deal with suppliers from all over the world, which means working ~24/6 (plus a seventh day to get her own work done). And has the generous "unlimited" vacation that translates as "no" vacation, unlike software companies that (generally) encourage you to take advantage of it. And makes midwest salary while living on west coast.
Btw my bachelors was in Mech too :-)
Software engineers may have simulators to allow testing SW at home, but mechanical engineers also have their 3D modeling and finite element analysis that they can do at home. Oh, and redlines and pushing PLM paper work should be doable at home.
I'm not saying its one-to-one, but MEs and SEs in robotics both have things that can and cannot be done remotely.
