The project supporter is there for you for the entire duration of the project, also as a coach. Make use of this opportunity and support. It is essential that you are active when it comes to challenges, and that you actively engage the project supporters. You know the state of your project best. You can make use of all communication channels in order to do so. A face-to-face meeting is often helpful and motivating. Problems that seem overwhelming and unsolvable at first might are on their way to getting solved the moment you address them.
