I found this post after reading your blog about cherries. The Ted talks sound intriguing, but I was more impressed by your opening paragraph. It's been many years since I had to come to terms with work stealing time I used to think was mine. This hard reality hit me the first summer I committed to a job that wasn't part time or temporary.
My university degree was in sight. "School", as a profession, was over. I realized I had crossed a threshold into adulthood and the realization was brutal. The innocence of youth had been defined by summers off.
I hope your business becomes a success and you can leave the factory job behind. Better to decide your own hours than to be obliged to fit your life into someone else's schedule.
