I have recently taken up tennis to stay fit and try something new.  
It's not easy to be a beginner when you're in your early forties; you 
have preconceived ideas about how things should be based on experience 
and perceptions.  During my first few lessons I literally attacked the 
ball.  I had Wimbledon on my mind, Maria Sharapova, the Williams 
sisters; I felt like I had to be larger than life, hit the ball hard, 
slam a serve into the box.  But I had it all wrong; I had no poise.  I 
went at that ball like I go at my life sometimes, afraid and driven by 
adrenaline to overcome my fears of not getting it right.  You don't make
 for a good tennis player when you are a Tasmanian devil whirring across
 the court.
What I have learned to seek is poise.  Equanimity.  Self-possession.  I seek to possess myself and not be possessed
 by fear or anger or stress or angst.  Perhaps if I find poise in 
tennis, I can find it in other areas of my life as well.  But what is 
poise exactly; what are its components?  Sure poise stems from ability, 
and ability implies confidence and experience, but also some luck, as 
well.  It takes time to develop poise; it takes conviction and patience 
and perseverance.  It's a practice, just as meditation is a practice.  
In meditation, you learn to sit through things and breathe.  You learn 
that the things that possess you have a time limit.  You learn 
patience.  You learn to see the subtle progressions that imply change 
coming.  So you stick with it, in hopes that change materializes.
I
 have started to see those subtle improvements and I've started to 
believe that you really can teach an old dog new tricks, that the mind 
has a certain plasticity, an ability to stretch beyond its usual states 
of functioning.
There's substantial evidence of this plasticity or neuroplasticity,
 as it is called, in the individuals who have suffered traumas and 
injuries to the brain.  In these extreme cases, brains have recreated 
neural pathways to rebuild lives.  Dr. Jill Bolte Taylor, the 
neuroanatomist who had a blood clot the size of a golf ball in the left 
hemisphere of her brain was "just an infant in a woman's body"; she 
couldn't talk, walk, read, write.  It took her eight years to regain her
 functioning after experts deemed it impossible; her TED talk has become
 an internet sensation for its hopefulness in documenting the expanse of
 the human mind.
So if a brain can rebuild a life, just imagine what it can do for your serve.
There
 are other neuroscientists jumping on the band wagon.  Richard Davidson,
 a neuroscientist who studies the brains of meditating monks exclaims 
that "change is really the rule rather than the exception"and it is up 
to us to choose the influences that will rewire our consciousness.  In 
the meditating monks, Davidson measured brain rhythms as indicated by 
gamma oscillations; the more gamma oscillations, the better the clarity 
of perception.  This allows for "a richer, more encompassing sense of 
what it is to be human."  
Davidson emphasizes that the key to changing the brain is practice.
Marie Pasinski, Harvard neurologist and author of Beautiful Brain, Beautiful You says it best:
Regardless of age, your brain has the ability to make new neurons and 
construct new neural pathways throughout your life. When you engage in 
new experiences or think in novel ways, new pathways are forged. Every 
time you think a specific thought, a specific pathway of neurons fires 
up, neurotransmitters are released and synapses are subtly altered. With
 repetition this pathway is strengthened. 
In our 
overstimulated society, it only seems natural that an antidote present 
itself.  Even famous role models out there are doing it - turning 
inward, searching for poise using meditation and the like.  In the 
trailers for the new season of Sesame Street, Cookie Monster is studying
 the martial arts, discovering that "a little self control can go a long
 way." 
Well, if a blue furry puppet can find poise, then surely it is attainable.
