Wow! I've already been contacted for 2 speaking engagements next month at local elementary schools. I love talking to students (of all ages) about my writing, and about going for your dreams in life, no matter what your age is.
I'm a pretty good example of starting later in life! I don't have any regret or sadness, either, that I didn't begin writing sooner, because I truly believe I had to live & experience all that I did, to be able to think and feel and write the way I do.
Life's great! No regrets here!
