When bad things happen weigh them fairly against your deepest anguish and upheaval that you not only survived, but also lived to perhaps share your story and inspire others.
In business, small things that appear outside your control can happen all the time, such as the awkward customer who is never happy regardless of what you do, or the company that's not paying your invoice despite frequent reminders.
The issue isn't really about the jobs that went to someone else, or the awards or the roles. Those disappointments are devastating, period. But it's how we fight back, not to show that they were wrong, but to convince ourselves we were right.
