Asking for feedback and testimonials can be the best medicine for inspiration ever.  By getting outside feedback it fuels your passion to keep creating because you're receiving outside acknowledgment.  You can also get help to redirect what you're doing.  If you're doing something that doesn't feel like it's getting acknowledged then maybe there's something out of alignment. 
I just asked my core support group for feedback and testimonials of how I show up to them.  I received some of the greatest compliments I've ever received in my life by just asking.  One person even said they are who they are today because of me...wow! 
I highly support my clients to ask for feedback every time you work with someone in the work that you are creating.
