Denise Glower Swank (not related to Hillary Swank) gave a nice interview (less than 3 min long) to Kindle Direct Publishing (KDP).
Basically she asks any aspirant writer to persevere. In her case her kids (guess what number? ..you will be surprised – check the interview) did not know what she was doing in front of the computer typing long and hard. AFTER her first book got published she got support from her kids.
