Appreciate your partner for his/her efforts in dressing well, making dinner and numerous other things that get easily taken for granted. In our obsession with expressing love, we often forget to express respect for our partner. "Let your partner know you have noticed his/her efforts by expressing your appreciation, either verbally or non-verbally. This motivates the person to do things with renewed vigour. This goes for everyday efforts as well.
Sometimes appreciate your partner for keeping time house clean. Everytime you come across something you like about your partner, make sure you pay a compliment. Words are important but they are too superficial to sustain a long-term relationship. They have to be backed by action too.
