I don't know if there are benefits of breaks, especially if it is to avoid the hard stuff. The hard stuff is the only way through, I think.
This week I did not want to go the most I have ever not wanted to go. I thought I wasn't going to go right up til half an hour before hand, and then I nearly turned and walked away once I reached the door.
It turned out that we had a massive breakthrough. A truly massive and totally unexpected one.
And to think - I could have been sitting at home feeling worthless and hopeless instead.

I think it is the hardest to go when the going gets hard... but that is also when it is most important.
