I am the bread winner in my family and have written for 15 years, I work full time and have children, my tricks are:
1. I'm not a good homemaker and don't care. If you want great food, marry a cook
2. I told my family early on that there's a certain time late at night I'm working https://twitter.com/kpanyc/status/1336724538059612163

I can't be everything. I'm a shitty homemaker but I never wanted to iron shirts or darn socks.
But more important than that, my husband knew early on I was serious about writing. My children too. So I have never felt guilty saying 'goodnight everyone, time for me to write.'

I've never had anyone magically taking care of shit. We emigrated here, meaning I had no family in Canada. And then to make ends meet my husband always worked, until this year, a night shift and I worked a day shift. We would meet like Ladyhawke.

I could never live to the rosy expectations of motherhood, so I just stopped reading advice columns about parenting and figured, eh, a large helping of mac and cheese never killed any kid.

Number 2 is really important. Don't minimize your time and yourself. If you have designated Thursday morning as writing morning, don't let your roommates, friends or family members barge in and interrupt you. Let them know that's your time. It's harder on small spaces--

For 12 of those 15 years I wrote on the couch with headphonesn or in bed because I didn't have an office and people got used to not tapping my shoulder or pointing at the TV. Sometimes I'll say "in 20 minutes" if I'm really needed and ppl learnt not to huff but wait 20.

And obviously not everyone writes 10,000 words a week and you have to figure out how productive you are, etc. So you shouldn't feel terrible because you 'only' wrote 400 words in a day. I scribbled during my commute, too, and 400 a day is a short story in a few weeks.

If you start designating a half hour as your writing time each day, defined not only as mandatory writing but also the ancillary researching or reading that you also need, you'll both a) get into a healthy habit b) get others in your life used to the idea that this is your time.

Oh, and my friend just mentioned something important: at different points in your life you will have different priorities. Writing might not be one at one point. I think if you like writing, staying connected to it is good. Journaling, adding stuff to your idea file, etc.

In the end very few of us have the perfect moment to write or that little cottage that shows up in movies. Most working writers I know juggle a bunch of things, go through ups and downs, so ultimately you shouldn't feel guilty or bad and just... Make writing work for you.
