I think that as humans we are more willing to change something when it becomes too uncomfortable not to. This could be a habit, a relationship, an occupation; anything we have accepted as ‘good enough’ in the past.
Signs will have been there, perhaps for a long time, that something is amiss, inauthentic, or just plain not right for us. But it seems to me that it will often require reaching a painful threshold before we take action, speak up, change, set new goals or let go.
Life is so much simpler if we pay attention to the signs. We act sooner, waste less time and feel more in alignment to our true selves. Yet is takes courage too.
