And I don't mean gun triggers.
I mean those everyday things that can trigger a memory, a sensation, an emotion. These triggers can be the true stuff of life writing.
Take this morning. I brew up the coffee and put some bread in the toaster. The toast pops out and as I am buttering it, I remember my secondary school English teacher.
I didn't like English when I was at school. Even though this teacher was one of the best I've ever had the good fortune to know, I didn't really like going to her classroom. It wasn't her, it was the subject.
However I've always considered her to be one of my mentors, someone who had a keen interest in my writing and took the time to actively support and encourage me. Indeed her interest in my writing continued after I left school, and goes on to this day along with a firm friendship we have enjoyed for so many years.
So what does all this have to do with a piece of toast?
Many years ago now, my teacher and her husband were packing up their house to move away. In a case of bad timing, she broke her arm or wrist, I can't remember which, was in a cast and so couldn't do a whole lot of packing. I came over one day to help. When it was time for lunch, we downed tools and prepared some soup and toast.
As I was buttering her pieces of toast, she said, watching me closely, 'Butter it right to the very edges.'
Every morning, I butter the toast to the very edges so even the crusts are included.
I could write a whole lot more about this very special teacher who invested so much of her kindness, patience, and energy into my writing at a time when it was so needed - and all it takes is a piece of toast and a spread of butter to get me thinking about those memories.
Have a look around you right now. Are there some objects that trigger a memory for you? Perhaps it's the scent from a vase of flowers on the dining table that takes you back to a soft, shimmering summer day, or an expensive writing pen that your Dad gave you when you were 21 (remember how special that was because he so rarely gave you anything?), or something as simple as the way sunlight glints off a wave in the bay, reminding you of a sailing adventure on a small boat with someone you really didn't like too much.
Be open to triggers, be watchful, be observant, jot the thoughts down in your notebook for later when you're looking for something to write about.
