I sympathise with you Coragem.
At the moment, I seem to be able to only get a couple of hours a week in. I work nights, my wife works evenings from Weds-Sat and a full day Sun. I have next week off work but much of that will be taken up with decorating the house. It's very difficult for me to get in enough time to have any sort of relationship with my wife, let alone write anything.
I don't get a full morning's sleep between Weds-Sat as she starts work at 2.30pm so I have to be up by 1.30pm (I go to bed at 7am) to get her to work and by the time I've dropped her off it's almost impossible for me to get back to sleep when I get home.
I was going to turn this into a big 'feeling sorry for myself' ranty type thing, but I'm sure none of you want to read my griping.
Normally, I'd make an hour or two to go and sit in the local with my best friend, who offers a bit of feedback here and there. Unfortunately he's off on the other side of the country at the moment and won't be back until I come back off holiday. It tends to be these times when I get the most stuff done.
