First, congrats to those selected. For some it may be a goal they have pursued with intensity we will never know and every young man deserves their selection.
In recent years, it has always been a challenge of mine to keep those boys who have not been selected for a team to keep going and not give up. From experience, I do find that many who miss out at one time and keep pursuing their goal with dogged determination and never give up either find they achieve what they want in the end, or it provides a skill that allows them to go on and achieve greater things elsewhere. Those that give up or take selection for granted will not achieve anything of note in the future.
I tell the following personal true story to those that are disappointed:-
As a schoolboy. I was lucky enough to get selected in some young rep teams, but there was a kid who I knew from another school who always just missed the cut in those young sides. And I remember seeing him very upset at non selection on at least the first time. Later on through school, I didn't make the teams, but assumed this guy did because I thought he was that good, he had all the skills and I thought he dominated the game every time I played against him. Many years later, I ended up working with this young man where we both had casual jobs. At the time we were about 20. He had just got selected for an Austalian Development Tour to Europe. I remember he was so excited. And I said to him "Why are you so excited? Haven't you done these trips and tours before for Schoolboys and u19's?" He said no way, this was the first representative rugby team that he had ever been selected for and he was over the moon. For at least eight years he had been overlooked many many times for any representative team at every age group level going in QLD. But he had persisted and then went on to reap the rewards. His name is John Eales.
I guess the question these days, that I do not know the answer to, would a player like John Eales who gets overlooked all the way through junior development up to u20's, find a pathway into representative (incl Super) rugby now?
