Great question Dom

I think this is one of the most important questions. If you find yourself able to say Yes to life as it is, how do you stay engaged in life. A attribute that is helpful is being able to hold what appears to be opposing ideas at the same time. Getting comfortable with Paradox

The test of a first-rate intelligence is the ability to hold two opposed ideas in mind at the same time and still retain the ability to function. F. Scott Fitzgerald

How to remain engaged in life and Accept (say yes) to the life (the moment) as it is?  How to “be grateful for the thing you wished most never happened” – Steven Colbert   How to “Participate joyfully in the sorrows of the world. We cannot cure the world of sorrows, but we can choose to live in joy.” – Joseph Campbell

My understanding of Buddhism engages the idea of Detachment. This is not indifference which would lead to the issues of stuckness your concerned about. Detachment is the practice of acknowledging/accepting the moment as it is without attaching a sense of self (ego) to the experience while living your truth and engaging in that moment. Can you hold the two seeming opposing actions of accepting the moment while living your truth to engage that moment?

This is action coming from a place of humility, honesty… vice anger, revenge… If one is in a brutal relationship the task is to see the relationship as it is and as Anita mentions changing what you can. Love may require that relationship end. Accepting the situation as it is in that moment does not mean you don’t stay in that situation. Accepting may be recognizing that you can’t time travel to undo the moment. Accepting is Seeing the situation as it is and acting on your truth as you know it to be in that moment.

Perhaps the problem comes down to how we define the word ‘Accepting’ ?  If accepting is a surrender you will likely end in indifference. But if acceptance is seeing things as they are then your in a better position to recognize what you might influence
