Sometimes after starting something new we long for what is old. The old might not have been better and could even been a little worse, but we still seem to have some desire to return to some part of it. I think this is probably, because new things cause discomfort and the old seem like a comfortable warm blanket on a cold day. Eventually, the new thing becomes not so new and gradually becomes comfortable and we can see things in perspective, but getting there is a pain.
