Why are people so obsessed with Pets.com? We shut it down and returned money to shareholders. Besides, there were plenty of other dot-com failures around then.

I always had a deep respect for people who started businesses, but now I cherish them. There's a lot of anxiety and blood, sweat, and tears that goes into this, and I love it.

When you fail, things get real. In fact, they get real real. If your success was a high profile success, then your failure will be a high profile failure. Opportunities and 'friendships' will evaporate. Failure shines a bright light on all relationships. The ones that last are pure and true, which is a true gift.

Do not wallow in your failure. Spend some time grieving, learn from it, and then move on. Constantly replaying what went wrong will not benefit you. Get involved in another company, another cause, another relationship.
