Edi-borials are not in-fconded. as looturettes, hov/evor they may be written to
to obviou. s; to others somovi. 'hat
point ou-b certain facts, which, some may appe:u?
a'bs-bract.
Some yews ago my Father remarked to me " One gets ou.t of an or gn.ni s ati on
what one puts into i-b. " At the time the statement seemed. v,igue - perh.ips even slightly
graniEioAioally incorrect,
Mter I had reached the age of manhood ( I was going -bo say maturity, but I
don-fc wish -to leave myself open -bo the cynics ) like M?j?k TTArain I began -bo realise the
OM had le.irned qui'fce n lot since I was a kid.
OK, I'll get to the point. Especially since joining the Institute, being
on Council, and even ifter being "pooled" into jobs ( ieo Bulletin Editor ) I have
" got the message " - for what li-ttle I have done I have re.-.ped a greater araoun-t of
pleasure. The friends I hnve m.ade, the help I received, has many -fcimes nore than repaid.
To -those who have not realised -this from the Division - well - all I can say is,
perhaps you. have not done nny-bhing for you.r Division*
