Everyone wants to win.
It is a given that it can be very frustrating and disappointing not to win, whether your effort is on winning a proposal for new business, court case, leadership position, or any other goal you set to achieve.
To win and experience are deeply entwined. You do not lose by not winning.
Instead, you gain valuable and tangible experience particularly when you fail at attaining the goal you initially sought. When you win you focus on the win, full stop.
