I believe encouragement is good, but I also think if you're really inclined to make something happen, you will do it with or without a push from another. I'm a doer and I don't need anyone prodding me to get going. On the other hand, I do appreciate knowledge and ideas for my project that I may not know I don't know! That could certainly be considered encouragement.
Any positive energy that's coming to you is good. It's good if it simply validates your idea, compliments you in your ability, and especially if it gets you moving in the direction of making your dreams come true!
