I've previously talked about the importance of focus. For example, a few months ago, I talked about why startups must focus first on the problem, not the solution. A few days ago, I talked about the need to refocus from time to time.
There's another side of focus that's rarely discussed - focusing (and often obsessing) on reasons you might fail versus focusing on reasons you might succeed.
The recent reactions from the developer communities to moves by Apple and Twitter underscored both the importance of making sure that you don't tie your business to that of another company, and also the importance of making sure that you obsess about and focus on success - and not so much about failure.
At the end of the day, even if there are 99 ways you could fail and only 1 way you could succeed, there's a very basic and undeniable fact: you can only succeed if you focus on the 1 way you can succeed. Focusing on the many ways you could fail will NOT lead to success. I discuss this in the following video.
