Success is easy. If all you want is some kind of success, getting it won’t be very hard. So it’s essential to know what kind of success you want.
Vast majority of the people either didn’t like Google Buzz or they weren’t as excited about it as Google would have wanted them to be. But there are people who like Buzz. And many of them are upset that Buzz is being killed. If you look only at those users, Buzz is a success. Same with Google Wave. Wave is still up and running, and those who’ve seen the possibilities of Wave are still using it. If you look only at those users, Wave is a success, and there’s point in working on improving it.
But Google decided to dump both Buzz and Wave because they want a different kind of success. Success is relative. Do you know what kind of success you are after? Do you know what kind of success will make you feel good about yourself? Discover that first—achieving it won’t be too hard.
