The willingness to turn to the Savior, the opportunity of going to sacrament service on a Sunday, and really participating in the ordinance of the sacrament... listening to the prayers, partaking of those sacred emblems. Those are opportunities that really help us to come within the ambit of the Savior's Atonement.
Any opportunity to serve in the Church is a blessing.
There's an old maxim which is really true for every parent and that is, 'You haven't failed until you quit trying.' I think that means both in terms of taking appropriate opportunities to teach one's children the right way, but at all times making sure they know that over all things you'll love them.
