Stepping into a journey ahead, not necessarily a smooth one but it may involve a windy road to reach the conclusion which will be a worthwhile one. Any change can be a positive thing. Consider the heights you must climb to get where you want to (mountains). The journey can result in a new future whether it be with someone or work. It can lead to a sense of freedom but it is a journey which needs to be taken (and wants to be taken). It is important however not to jump in to it, and do your homework first, be prepared and there should be no unwanted surprises.
I'm not very good with symbols however the butterfly represents to me a new freedom, bluebirds of happiness, and a fox for caution and being cunning and agile.
