If you’ve ever been successful at anything – even swimming a width for the first time – other people who want to do that thing will want to know how you did it. And you’ll probably be flattered to be asked. It’s nice to share the benefits of your experience in the form of hints, tips and advice!
Think what you’ve achieved in your life and work, and the lessons that can be drawn from it, then tell your story in a blog, ebook or printed book. People will appreciate your unique insights and you might even make a few quid e.g. I earn a steady stream of passive income from my books (both in Amazon’s top 100 sales & marketing books at the time of writing).
