Recently, he wrote about three techniques that can improve positive attitudes and performance. The mnemonic is BCS - behavioral, cognitive, solution-focused.
A behavioral approach can include meditation and neurolinguistic programming. The examples I have taught include visualizing yourself (during stress) in your calming environment (e.g. at the beach under an umbrella on a sunny day) and moving yourself into a "picture frame", allowing you to step back and separate the emotion from the event.
The cognitive approach relies on reorganizing our thinking using journaling (or blogging) and sometimes coaching or mentoring. Shaq discusses a life-changing conversation with Bill Russell he had as a young player. Shaq remarked, And then we just sat down and talked about his game. He was like, 'You should do this. You should do that.' And when you get information like that, that’s like one of the top techy guys trying to give you some stock information. You better take it, you know what I mean?"
The solution-focused approach reinforces "what went well" when we are in high performance, also known as "the zone". When we combine our analytic process that produces "an edge", with discipline, we optimize outcomes. Our task becomes to invest our time to "do more of what's working and less of what isn't."
