Getting rebuffed does not immediately feel good. It never truly will. Well-intentioned plans stopped in their tracks by someone in power. It's initially hard to swallow.
When you can see it as an opportunity for an alternate path you will save yourself a lot of energy.
Being rebuffed can be seen as a sign post you need to head down an alternate track. It is permission to leap into what you might fear but know is the most generative path.
It is a call sign to things that have not yet emerged but will if you give space and nutrients of time, effort and focus.
