As I work with clients that are USA based I have noticed a similarly unlikely expectation. They can't say no. They have no clarity about the difference between a want and a need, a passion and a calling, a Should and a Must. I spend much of my time listening to how ovwhelmed and overclocked their lives are, and how this whole experience just happens to them. I am deeply sympathetic. I understand pressures from multiple directions and sources. I get how many opportunities can come your way, especially at the peak of your working years. I resonate with the confusing options that come at even ordering food at a restuarant.
However, each yes is a no to something else, and each no a potential yes to some other more valuable event or activity. Only you are responsible for your yeses and your no's. I know you don't want to hear that, and I don't want that responsibility either, but there it is. It will never change. Ever. You can never escape from this, you can only choose. When you do not think you are choosing, you have chosen. There is no where to lay the blame, there is no one to lay this responsibility on, there is no one but the face you see in the mirror. There are Cadillac pickups, but they are neither Cadillacs nor pickups. Wants and needs are not the same vehicle either. Have clarity. See clearly. Chose. Or someone else will make the choice for you.
