"If all you have is a hammer, everything looks like a nail."

Prioritize writing readable working code first

Favor safety and maintainability

If beginner: resist the urge to optimize

If expert: delay the decision to optimize

/* public class ContactValidator : BaseValidator { protected override ValidatorResult Evaluate(Contact contact) { if (contact.ValidationState != ValidationState.AwaitingValidation) { //TODO }

}

protected override ValidatorResult GetMaxValidatorResult() { throw new NotImplementedException(); }

public override string Name { //TODO Confirm name get { return "Temporary Name"; } } } */
