I work from home only, and am fine with a desk in my bedroom (though I don't share a bedroom with my SO, so it's kind of an office space with a bed).
Biggest help for me is a regular routine of things that support me being happy/productive/creative. Here's mine:
- Journal every morning. Great brain dump and gets me focused, gets stuff "out of my head" and onto the page, into a list. (I'm actually following up on my "forum" note from today's pages). I used to have "oh shit, I totally forgot..." but now I never do. I've been doing 3 pages of handwritten journaling "morning pages" for about 7 years. I've skipped maybe a few dozen total days (including vacation) in all that time, and most months never miss a day because I value it so much.
- Read motivational books at breakfast. Since you're not around other people to pump you up (or drag you down), I found it useful to get advice, motivation and ideas from trusted reading every morning. I read at least 15m at breakfast, everything from Buddhist philosophy to sales training - anything that feels helpful to my work, productivity and creativity. Nonfiction in the morning, fiction at night.
- Block time. I find it best to work for about 60m solid without any distractions (web browsing), then take a break. Then I'll get up, maybe refill my tea, play a quick game or whatever for about 10-15m. Then dive back in for another hour. I use timers a lot. If I have something I'm really avoiding, I give myself a 15m timer, and quit after 15m unless I suddenly love it.
- Exercise Daily In my experience, I work more efficiently and densely than any time I worked in an office. I often need to blow off steam for focusing that much. I walk every day, outside of more rigorous exercise, to help integrate my learning and walk off the day.
- Meditate Too much to be said on this topic, but I couldn't live without this. Been sitting regularly for about 15 years and find new things to appreciate about it still.
- Checklist I literally have a checklist with all of these things, plus "What other successes did you do today?" to help acknowledge what I'm doing and see what's useful. I take notes on it, and it is actually super helpful if I feel like "I did nothing today," and then I fill out the checklist. Happy to send you my version if you want to modify it for yourself.
