You can never set “big” enough goals to keep you motivated and working everyday. A more reliable process is to set goals that “mean” enough to you that you are inspired to keep working every day. Inspiration is defined as imbued with the spirit to do something. That can only be accomplished through meaning. Consider that the bigger problem is that you are looking at your current work as “hard”. A far more powerful idea is to change the relationship you have with work. In my book Creating Sales Velocity I talk about writing a gratitude list every day. Try writing one just focused on work and notice that work gets easy, effortless and enjoyable.
