How do some people do it?

I told myself that I would utilize this "tool" as a way to share and stay in touch. However, the biggest challenge is finding the time to get in front of the computer and sit to write. I am on the computer most of the day as part of my livelihood. So, when I return home, often I am doing other things and it is not computer related. So, I wonder, how do some people do it. ? I am going to have to try something different to be able to successfully incorporate this into my activities.
