Working 40 hours can be tough. I think it is about a finding a setup that can work for you. Here’s how I set it up to work for me (I work more than 40, so some of this is just so I don’t die). Maybe there’s something in there you can try out.

• I work with family so I can double up work/family time
• I work from home so I don’t have to commute and I can pause to see my kids off to/come home from school
• My husband does not work so I see him throughout the day and he takes care of household chores
• I let my kids play in my office when I’m working (even on conference calls)
• I like my job and coworkers
• I take naps on the weekend
• I have given up on hobbies outside of what my kids like
• I get up at 4am and start work most days by 5am to ensure I have evenings with my family

I lost several hours to Esperanto on Friday: https://en.m.wikipedia.org/wiki/Esperanto
