“While smaller schools may be playing both sides of the ball,
or “Ironman Football,” larger school athletes may be able to
hone their abilities at one position... A large school athlete
may spend more time with coaches... This increases the
number of focused, directed practice hours an individual
obtains in a given season.”

Does “elephant” control predict
college football starting status?
Long-term
The significant psychological subscale was:
1. | maintain emotional control
no matter how things are
going for me.
. When things are going badly,
| tell myself to keep calm,
and this works for me.
. When | feel myself getting
too tense, | can quickly relax
my body and calm myself.
. |remain positive and
enthusiastic during
competition, no matter how
badly things are going.

International chess grand master at 15.
¢ Started playing at age 6
¢ At 7, began weekly tutoring by

¢ At 12, joined one of the strongest
chess clubs in the world and met
several times a week with chess
master Jack Collins with access to his
library of chess books.
Result: Mastery in 9 years instead of 10 (probably
resulting from intensity and hours of training).

Wolfgang Amadeus Mozart
"By the standards of mature
composers, Mozart's early works were
not that outstanding.... Of those
concertos that only contain music
original to Mozart, the earliest that is
now regarded as a masterwork (No. 9, K
271) was not composed until he was 21.
By that time Mozart had already been
composing concertos for ten years."

The Beatles
¢° 1960 went to Hamburg, Germany «
to play in strip clubs 8 hours a .
night, 7 days a week.
¢ The Hamburg trips yielded 270

¢ By 1964 when the Beatles came
to the US, they had played at
least 1,200 gigs (~8,400 hours).
“They were no good onstage when they went
there and they were very good when they
came back... It was the making of them.” From
Shout! The Beatles in Their Generation (1981) by P. Norman.
