Perfection is something that is so desired yet so difficult to achieve. For me striving at excellence is far more easier and profitable compared to perfection. The fact that we are human makes perfection even more difficult to attain. But then, these flaws make life even more interesting, flaws give rise to excellence.
In relationships, I just believe you create what you want to see. You want a rich spouse, then encourage him or her to work harder and more creatively, support him or her, rather than making huge demands that make your partner feel inadequate. You don't want a lousy spouse, then encourage him or her to choose and count his or her words carefully before saying them out. Real Relationships require a great deal of work to raise and maintain. Relationships that last for life never started with perfection, rather they thrived on tolerating and managing flaws that could not be corrected.
