Physical, tangible actions I've taken after re-evaluating my self/worldview: deciding to work out, eat healthily, and walk lots; discarding the majority of groups of people I've come to know, keeping only the best of the best at my side (though many of the others are still perfectly nice people, they aren't of sufficient calibre to be of any use to me/my family/goals); "quitting" smoking (after less than a month, though - what's the point?); investigating music on progressively less rigid bases, so as to gain a greater, more personal understanding and appreciation; studying with rigour, for the first time in eight or nine years.
That's a relatively small list of some of the better changes I've enacted in my life/lifestyle relatively recently, as a result of ruminations.
