It's often suggested that writers should get up early. It's not for everyone, because being tired and cranky all the time isn't necessarily a recipe for success. And while some household chores can be put aside, sooner or later you have to do the washing up and laundry or you'll run out of crockery and underpants. That's where finding time comes in.
Most writers need a day job, which means a commute that can sometimes be reclaimed. If on public transport, or car sharing, there's the possibility for writing; if driving there's the potential for writing-related podcasts or audiobooks. This is time that has to be spent on commuting anyway, so it might as well do double duty.
Something that I found helped me find time was by paying attention to the travel times involved in getting to work. Leaving ten minutes earlier to avoid the traffic can make the the difference between a commute of 20 minutes and a commute of 50 minutes. Since there's somewhere I can buy coffee and sit down, that's another half hour of useful time found.
It can be difficult to pinpoint moments of time that are findable, and a spreadsheet or table can come in handy here. I wrote the days across the top, and the hours down the side divided mine into half hour slots. The first things I filled in were the unavoidable tasks - day job, getting ready for day job, meals etc. Then I looked at what was left and blocked in time for unavoidable but moveable things, like family time and housework.
It turns out that I have more time to write than I thought. Looking at how I spend my time has allowed me to find between an hour and an hour and a half every working day for writing, and that's before I even get home. If I spent less time on Netflix and the internet I could probably make more, but finding time is like finding cash down the back of the sofa: you won't know it's there unless you look.
