First have stuff you want to do, second get it done.
If it's important enough for you to get to it, all the motivation and energy will be there, if you doing stuff to make other happy or to try to live up to others expectations, then you might want to consider if that how you want to be living.
We all have responsibilities Family, work, friends etc and each one needs our attention is a number of different ways, if you go with the flow and what make you happiest, you might find you be getting a lot more done than you thought possible.
If your having to force yourself in to doing, thing's outside your general life responsibilities, then, then ask yourself what are you getting out of that, and is it worth it.
Ask yourself what are the differences from the things you have done in the past that you wanted to do and enjoyed doing, and thing's you just did, and did them half heartedly.. what are the mental and emotional differences? and if you had to draw each construct on paper what would each on look like? now of you was then to imagine making each picture life size, and was to first step in the the (-) and think about doing stuff how does that work for you? and what are you noticing in your thinking and feeling? and if you was to step out of that and shake it off, Then step into the (+) and think about doing things, what happens now, what are you noticing in your thinking, feeling and general sense of well being? Now ask yourself this, what are you not thinking about that if you did would give you all the energy and motivations to get things done? then use that as a stepping stone a guide to.......
