First of all, I object strenuously said the lawyer--no, really just me when it comes to the term "Day Job".
Day Job says writers work at night, which in most cases is true. But working for 6-8 hours whenever during the day and 7 days a week, is really a full time job, even with regular paycheck employment.
Writing is not regular paycheck employment. But instead of Day Job, I like the term, Regular Pay job.
Recently I was conversing with a friend, who had a friend (and a lot of writerly stuff goes like that) who wanted to write. But said the first friend, the writer-friend had a family and a job and didn't have time to write.
This lament is way too familiar: I have a day job and a family and I don't have time.
To the second party, my response is the best quote, gotten from a busy Regular-Paycheck person who said, "I write around the corners of my life." This says, he made time to hold a necessary insurance and benefits Regular Paycheck job, plus tend his family life AND write.
I'm impatient with this no-time to write excuse, based on my own experience. At one time, I did have a Regular Paycheck job, a family and two publishers. Two Publishers, so that said I was under contract to deliver manuscripts etc. at specific due dates. I did, so I know from experience that if a writer wants to write, he will make time, not find it.
Here we are in the busy season and still writing and dealing with necessary writerly business. Very difficult during the holidays. Or the summer. Or the spring, or fall. I'm writing full-time now and time and scheduling is still a challenge as business needs deepen as the career rises or changes. Now Facebook and Twitter and other promotional aspects take writing time, plus blogging, etc.
As for writing with a Regular Paycheck job and a family, watch for the next installment of Writers Survival Guide and I'll lay out my schedule. You may have some tips to share, too.
