That happened today. I am only now getting it together to be on the computer, past 7 PM on a Saturday. Tears, emotions, just one of those days. Mostly due to naysayers, and personal feelings, and regrets. I have to learn to shield myself better or just stay off Facebook. Anyway, no one's fault but my own for buying into a conversation with a negative person. Will be the last time for me.
So, now that I am back online, thought I'd just mention that with a MOOC (Massive Open Online Course - like we have been discussing, Coursera, in particular), you can make up your own hours. If you are having a bad day, take care of yourself! It is okay.
Of course, if you are doing a class for CEUs (Continuing Education Credits, usually for a medical profession or a job requirement), then stay the course. And if you have paid for the Signature Track which allows you to get confirmation/credit from the university for your work in the class, then, again, stay the course.
Take care of yourself, and enjoy life. It really is too short...
