Just keep plugging away and try not to worry too much about how long it will take or what the end will be like. Somewhere along the line I learned to try to just take things one moment at a time. The alternative to was to spend too much time worrying about the future (in all sorts of aspects of my life) and I just couldn't keep living in that kind of stress and anxiety. I've learned the best I can do for myself is to try to be in the present moment and let the future moments be in their own moments rather than today.
