So you claim you don't define yourself, not even partially, by what you do each day...this thing you do for income that is also a skill you learned or a trade you practice? You claim that it does good for others, but that there is no part of you in it?
You can see why that statement is suspect, can't you?
or, if you agree that people do not define themselves entirely by what they do, but that it is a consideration and an important one, that you do not do so because you find it sad/pathetic? Why?, in order not to seem sad or pathetic yourself, to yourself?
You can see why that doesn't work as well?
Good luck to you if you paint yourself so easily into a corner at whatever it is you do that you're so ashamed of each day. Certainly if you won't allow it to be a part of you at all, yet must spend so much time at it, you must have some difficulty with it?
Why would you believe that a person who enjoys what they do, associates with others who do the same thing and doesn't take the time to lay out for every stranger just who & what they are beyond the task they perform unable to define themselves?
c'mon junior, I've got a can of paint thinner if you can just reach it.
