Conciously replicate the feelings you had when you started.

Your seemingly unlimited drive is not something providential, it is something you can 'conjure' up, by consciously shaping your every thoughts:

Try and go a day focused only on the most awesome outcome of your goals. Actually imagine and feel that outcome as if it already happened. Do this constantly and before you know it, you will suddenly have the same 'Hyper-interest' and motivation you had in the early beginnings.
