I love the article I Stalked Steve Jobs in Forbes, detailing how a junior CEO got time with Jobs in the 90’s … all about persistence:

I was a young CEO and I needed answers. Steve Jobs had them. There was only one thing to do.

So I sent a FedEx letter.

Then I sent another.

Then I started calling.

Then I sent another FedEx, and called some more. Finally, after 7 FedExs and 12 phone calls, Steve’s assistant said he wanted to talk with me.

He then offers tips on how to get to a VIP, although she did not include one of my old favorites – call at 7:30am before their assistant gets in. Shocking how many times that one has worked for me (As long as you try it enough times).
