Learn to love your children unconditionally. Remember that they are individuals who, like you, are developing their own view of the world and want to live in it their way. They don't want strings attached in their relationship with you. They need your love, support and guidance. If you put expectations on them to be or do something in order to gain your love and approval, you may lose their love and respect.
Many of us have had the pleasure of raising the good child. While this can be a no-stress situation for us, for our child it can lead to learning poor behaviors.
The good child may be ignored or worse have too much trust/responsibility placed on his or her head. This can lead to behaviors that will show up in adulthood as trying too hard to please. Remember to pay attention to the good child and not give them too much responsibility.
