What "work" would you do even if you didn't have to?
For me, it was writing. I have been writing in my journal for close to ten years now without missing a day. I never considered if people would eventually read it or not. It has been something I've looked forward to doing each morning and evening (and sometimes throughout the day). It's encouraging to look back at the progress I've made and read everything I've learned.
My daily practice of writing every day has now turned into this blog, my website, and a few books I'm working on. It's been scary to put my thoughts out there. I know I can be vague and sometimes speak in riddles, but that's how I like to write. Turns out, it's what people like to read; short, meaningful sentences that hopefully make you think.
