One step forward, two step backward.
You have to work with the clubs and schools. Make training in regions 1 or two days a week. Get the clubs and their coaches involved and work on a plan that that will build confidence and work on players short coming.
Have local and overseas camp with accredited instructors and experience individuals on the off seasons. You can't take out the players for extended time from their clubs but you can create a system that cover it all. Many countries have been able to do it.
- Don't let negative things break you, instead let it be your strength, your reason for growth. Life is for living and I won't spend my life feeling cheated and downtrodden.
