Agree with a lot of what you say. At the first stage of your essay I could not think of any limitations I am imposing on myself but after reading to the end of your post have to admit there probably are houses of cards that I have built or that have formed around my concept of my self. The idea we have of our self- of what is important to us and what we strive for or want or hope for is to some extend unavoidable imo. In placing limitations we also create context- imo it is difficult and potentially counterproductive to seek to remain entirely open to all possibilities when in reality we can only achieve if we focus on limited aspirations. Of course keeping an open mind is good- but lacking any firm convictions or ambitions can also create problems. Freedom is having nothing to lose... Hope this makes some sense.
