I only read the first page of this so sorry if its a repeat.
but what i would do is take a break. and wait until the desire is back... trust me it should come back ill give you an example I played Proffesional poker for 5 years and have played poker for 10 any way i was good at had 4 consecutive winning years (the first year wasnt a winning year
) anyway about 6 months ago i started just going through the motions cause i needed to do it to make money. so about 3 months ago I told myself "seth why do it if your not happy doing it?" so know I am going back to school to get my Bachleors degree for business. but now im starting to get that flame back after about 3 months so dont give up i havent i just took a break. So im starting to practice so i get that killer instinct back. well Goodluck and PS probably just a midlife crisis. youll pull out of it
