Closest I can come is:
Augustus(Gus) McCrae from the Lonesome Dove series. He's a bit more extroverted, and I've tamed down a little as I aged where he stayed a little more wild. But the outlook on life, the fun until I'm needed to get serious, the sitting around philosophizing while others are just tasking. Of course, part of this comes from I read where his character started from youth in the first two books in the series before the famous movie/book. But, yeah, he's sorta an exaggerated character of myself.
