Perhaps taking things in small steps rather than lumping everything that needs doing together. If it seems like a mountain, then you won't get the motivation. Make a list of a couple of small jobs each day and do them before you do something pleasurable - I do this to myself sometimes - treat myself like a child lol by saying, for example - "no computer until I clean the dishes" You can also give yourself a day off where you don't do anything and don't feel guilty.
