I was thinking about what you said this morning and you are 100% right.This is what it's all about. Don't count the hours, the more hours you work the less productive you are being. Streamline everything. You did not leave the world of 'normal work' to go and sit down in front of a computer for 8 hours a day in a different location.
Work smart, not hard.
I (like most people who work full time) have been conditioned to think that work in 30-37-40 hours a week and obviously now I've made that job me doing 2-3 hours a day feel weird and as if I should be doing more but that actually isn't the case at all since I'm not being paid by the hour anymore!
