This principle is true to many areas of our lives. If we are talking about a close romantic relationship with another person or making a decision to move from one business to another the same principle applies.
It is impossible to appreciate true change and growth until we are able to let go of the past. We learn many lessons before we exit but the ongoing lack of closure causes the entry into new relationships not to be able to grow and florish until we make that decision.
One can never truly grow until you let go and risk the space in between. There may be many great expereinces, relationships and skills to be gained.
Are you brave enough to exit?
