try and try again

Suddenly i remember a friend today, Papank,
who died in Sept 1996 just after he graduated.
He ever wrote:
if you try and you fail, don't give up... just try again.
if you fail again, just try and do it again.
if you fail and fail again ..
keep trying and trying again until you succeed.
bcoz once you stop trying then all you've done in the past
will become NOTHING and totally lose its meaning
