It is difficult to suggest one minute strategy as such, however there are lot of things you can do to make your partner feel loved and appreciated. One of the easiest ways to do is to thank them for the simplest of things. For example, if your wife cooks daily for you, thank her and tell her how much you appreciate it.
Also, compliments mean a great deal - compliment your partner about how they look, how they handle things, etc.
Leave small notes saying you love them, in a place where they least expect to find them.When they find the notes they will be pleasantly surprised.
Its the small things that count in life and i am sure your partenr would appreciate it.
