One thing about Apple is they have these fanboys - as I always say, 'Sell to the people who love us.' For example when they came up with iPad mini, everyone who had an iPad went out and bought a mini as well.

Stay the course and keep building an integrated Apple ecosystem of iPhone + iPod + iMac + iTunes + App Store + Apple TV. No one has yet demonstrated they understand how to create an 'experience-based ecosystem' as well as Apple.

There is a difference between what technology enables and what historical business practices enable.

These young people need to see that there's something bigger out there than what they're looking at everyday or seeing in the news or on social media. They need men and women to come into their lives who will give them a bigger vision of the world, of life, of opportunity, of what they can become rather than what they think they are limited to you.
