"Going with the flow" is for some people an excuse for not taking action and it refers usually to one's life situation.
Eckhart TolleSurrendering only refers to this moment, whatever "is" at this moment - to accept unconditionally and fully whatever arises at this moment.
Eckhart TolleWherever you are, be there totally. If you find your here and now intolerable and it makes you unhappy, you have three options: remove yourself from the situation, change it, or accept it totally. If you want to take responsibility for your life, you must choose one of those three options, and you must choose now. Then accept the consequences.
Eckhart Tolle
