I remember reading that it takes about 10 years to master a craft.
It takes anywhere from 6-10 years to get great at something, depending on how often and how much you do it. Some estimate that it takes 10,000 hours to master something, but I think it varies from person to person and depends on the skill and other factors.
I've been taking pictures since my children were born—that's 30 years. But I didn't begin to take my craft seriously until 2008 when I first began a blog, and I didn't begin a dedicated practice until 2016 when the crushing blow of my mother's dementia led me to photography, like medicine for me. I'm only beginning to set my foot firmly in the craft of photography.
And somehow, knowing that it can take a decade to master a craft is comforting. There is time to learn.
