As writers, we encounter a lot of rejection. Not only from publishers but from our families and friends too. Although the latter doesn't happen so much anymore, I experienced a lot of it in years past. It's very hard to convince your family that writing is what you want to do. It's not right of them to demand proof of your passion and dedication, but many do demand it. Some also seem unaccepting until you secure a "real job" as well. It's as if as long as you're not a starving artist, you can make as much art as you want. That's why it's really important for writers (or any artists) to have a supportive spouse: one that is unconditionally supportive. Not only are these cutesy notes necessary to boost self-esteem, so is the spouse's involvement in the art. If you're like me, you put more emotion into writing than you express to actual people. Writing can be lonely in that way. That is precisely why it's important for husbands and wives of writers to actually READ their spouse's work. Although my character's beliefs are not always mine, I tap my memories in order to fill those beliefs with true emotion. Your relationship with your spouse can be incredibly intimate, but there's nothing more intimate than dwelling in another person's art. You see the worlds within their mind and touch parts of them hidden deeper than perhaps even they know.
Support goes much deeper than saying "I support you". From love notes to tidying up an individual's writing area to reading a story she/he wrote and discussing how much you enjoyed it, an open mind and support from loved ones are sometimes more important to writers than publication.
But publication is rather cool. ;)
