When you have been working on a certain vision for years, sometimes you can get very discouraged. Especially; when you have put a lot of time, money, blood, sweat and tears into it. What I have found in my experience is, if you have been sticking to it that long, more than likely, your heart and soul is invested in it. Its beyond just a ego trip situation. It's not just something your doing it is something that you are. Its a part of you and as long as its coming from the love and compassion within you, than you should keep a "Full Sail Ahead" attitude. Your vision is already there, you are just going through the step by step process that's a part of being a manifesting spirit.
