After much research we purchased a book called 'The Exceptional Seven Percent: the nine secrets of the world's happiest couples'. This book is the fruit of many years research into what makes successful couples tick and how the rest of us can make positive changes by developing a marital imperitive; setting and achieving emotional goals; and cultivating exceptional levels of fidelity, loving, service, rapport, negotiations, gratitude, joy and sexuality.
Generally I hate relationship books (come on guys - men are from earth and so are women - get used to it!
) but I have found this one to be immensely helpful. It is practical, methodical, down to earth, provides concrete examples and real-life stories - almost the Jan Somers of marital investment!!!
For us, the reason we invest is so that we can enjoy our life together even more in years to come. It makes sense to us to put in the same conscious effort to cultivating our marriage as we do in cultivating our investment portfolio. Otherwise - what is the point?
