Here is the thing - there is only so much we can control, let it go. Do what you can then let it go, it is easy to forget in this world of expectations, pressures and management that what we do, is not who we are. A lot of what we do and worry about is self imposed, to try and be perfect, meet someones expectation, not disappoint. You cannot hand over everything, in maj's example, isn't it sad that we do not stand still at what was left behind - a gap left by a human being - and merely see that we were left with all the work?

My consulting friend, life is short, none of this is real and this too shall pass. Do what you can, then surrender to what is and let go of the outcome. Zen for consultant hath spoken.
