Sometimes we can put the development of our style... especially when you think of it as the development of ourselves, we can put it to work when things aren't going well, or we're having a gloomy day.  Giving ourselves a little project to do... clearing off the mantel and choosing something different to go there for a while, taking the time to create a bouquet out of several different bunches of grocery store flowers, making a simple throw pillow... these little bursts of creativity can give you just enough juice to boost you out of the doldrums.  Maybe hanging new curtains isn't going to solve your really big life issues.  But what about the small ones?  What about the daily feeling of blah that ends up sucking the life out of you?  Working on your style can help with that.
