If you build your business first because you want to make money, then you may suffer the BlackBerry symptom.
You need to build your business because you want to do good things for people. You have to start a business because you want to make a better World. If you have this in mind, then you will never fail.
BlackBerry did build something in the past and then they thought that the glory will never end. But the World is not like that any more.
Other companies like BlackBerry are BlockBuster, Microsoft (they are now offering Office for Android for free) and in a near future: Apple.
A new report has arrived to BlackBerry and their situation is not getting better. They are in big troubles... Learn to be updated. This is the future and there is no intention of stopping.
