There is always choice, no matter what situation we are in.
If in the short run we cannot change the outer circumstances, we have a choice to change the way we look at it and how we respond with our thoughts, feelings and actions. This in itself will change the situation.
If you are however in a circumstance where you HAVE a possibility to make outer changes and want to, but don’t, it’s mostly because of fear, in any and all forms.
As a general rule, I will say, breathe and go there. It is the place where liberation and freedom is offered. Not from the circumstance, but from the fear.
