By age 50 you have failed at something. The reason it may not spring to mind is because we conditioned ourselves to tell and retell our success stories while hiding our failures far away in the sub conscience. A failed exam or relationship, a botched task or neglected responsibility may haunt us in private but publicly we pretend they never happened. Yet picking ourselves up from failure always makes a great learning experience for ourselves and for others. The deeper we bury our failures the less likely we are to learn from them.
At 50 I know that however hard failure hurts it also creates opportunity.
— feeling optimistic.
