Everyone knows that you are sensitve - sometimes it may be just a little bit too much! Try to put your feelings to the side and listen to the voice of reason.
Your brain is working at full blast. You are creating new concepts and learning new things. Make sure that you don't listen to those who want to discourage you.
Don't give up if not everyone is fully appreciating your efforts. Take your time to think through what your critics tell you, it may inspire you to even improve your plans.
