Harlan Coben believes that if you're a writer ,you'll find the time; and that if you can't find the time ,then writing isn't a priority and you're not a writer. For him writing is 1 job—a job like any other. He has 2 it with plumbing, pointing out that plumber doesn't wake up and say that he can't work with pipes today.
3 , like most writers these days, you're holding down a job to pay the bills,it's not4 to find the time to write. But it's not impossible. It require determination and single-mindedness. 5 that most bestselling authors began writing when they were doing other things to earn a living, And today, even writers who are fairly 6often have to do other work to 7 their writing income.
As Halan Coben has suggested, it's a 8 of priorities. To make writing a priority ,you'll have to 9 some of your day-to-day activities and some thing you really enjoy. Depengding on your 10 and your lifestyle, that might mean spending less time watching television or listening to music, though some people can write 11they listen to music. You might have to 12 the amount of exercise or sport you do. You'll have to make social media an 13 activity rather than a daily, time-consuming 14 . There'll probably have to be less socializing with your friends an less time with your family. it's a 15 learning curve and it won't always make you popular.
There's just one thing you should try to keep at least some time for, 16 your writing—and that's reading. Any write needs to read as made and as widely as they can, it's the one 17 supporter—something you can't do without.
Time is finite. the older you get, the 18 it seems to go. We need to use it so carefully and as 19 as we can，that means prioritizing out activities so that we spend most time on the things we really want to do. If you're a writer, that means— 20 —writing.
