Your "general" coaching philosophy must be just that ... YOURS. It's what YOU believe.
That said, you must adapt your philosophy to match the resources available to you. How good -- and many -- are your players? How much does your community EXPECT? Do their expectations match their support and your resources?
Are YOU willing to compromise your principles?
I have coached big/small, public/private, boys/girls, no resources/unlimited resources, no expectations/high expectations.
The only commonalities were: Be on time! Respect your teammates, parents, teachers, fans! No profanity!
It all flows from there.
Good luck.
