Consider your emotional bank account.
Several years ago, I went ga-ga over The Seven Habits of Highly Effective People. In all honesty, I didn't actually make it through the entire book, but I took copious notes on the first few chapters and those key principles revolutionized my life.
Start with the end in mind and plan the smaller steps that align with the end vision. Yes! (Applies to lesson planning, wedding planning, and deciding what to do with your "one wild and precious life").
Be proactive. Stop complaining about the things you can't change and get busy changing the stuff you can. Amen.
And a third principle: think about relationships in terms of an emotional bank account. Your positive actions toward other people serve as deposits in the account. Your negative actions function as withdrawals.
It can be so easy to take Matt for granted because we're in a stable, committed, relationship for life (knock on wood). It can be easy to snap at him when I'm tired or be petty when I'm immature. I have to remember, however, that those actions do work like withdrawals from our emotional bank account.
On the flip side, it's easy to make deposits. Frequently saying thank you, giving little massages, smiling, verbalizing compliments that might otherwise go unspoken, leaving notes, performing an act of kindness, etc. all help build up the relationship. Also, apologizing can do wonders for trying to make up for a withdrawal.
