One key ingredient in forging a successful relationship of any kind is to manage your own expectations. Nobody in this world is without fault, whether it's a spouse, parent, sibling or business partner. Problems arise when someone has set the bar too high for their significant other to achieve. Gaining an understanding that your own expectations for yourself may not be achievable by your partner is a big step toward relationship success. Many times, someone has such high expectations for himself that he feels like everyone else should as well. A father who was a straight-A student may need to manage his expectations when his son or daughter isn't. A spouse who has a type-A personality should manage expectations if their partner is more laid back. Just remember that lowering your expectations for someone doesn't mean she's is off the hook -- she still has certain requirements as one half of the relationship.
