I always felt that if I lost my method of making money, I'll find others. If a tool I used stop working or Google re-scored its algorithm, I could adapt. But if I lost my inspiration, I was stuck. My guess is that for you its the latter. Everyone is different and is inspired in different ways- for some, its finding a method you personally find exciting, for others its reading a poem or short story thats uplifting, still others daydream what life would be like when they're more well of and comfortable. One's mind can be very stubborn against working and concoct limitless rationalizations for not working if it isn't sufficiently motivated.
