This is a most interesting topic that has been started.
We must all remember that this is a sport and as such gives all the benefits,satisfactions and disappointments that you will get from participating in any sport.
It can be an expensive sport as I should know being the father of a fairly successful junior bowler.
But, like most things in life, you will get out of it no more than you are prepared to put in.
My son did not do as well as he needed to in his final year of high school and was unable to enrol in the courses of his choice, but due to the effort he has put into his bowling, the efforts of a great coach and a bit of good luck, next week he leaves for USA to study the subjects he wants.
Moreover, it will be tuition free and save me a lot of money.
So, enjoy your bowling any way you want.
If it is just for fun, fine - have fun.
If you want to play for Australia - go for it.
If your dream is to play in the PBA - set your goals and do your best.
Most of all - enjoy yourself.
