what happens next...

i have never known what is coming up in my life and actually take pride in the not knowing. in some way its very exciting to me. "go with the flow" has always had a special place in my heart. its not that i'm aimless. i have a great job, cheap house, nice little nestled life......but what happens next? i'm not at all unhappy, i love what i'm doing right now......but thats just it, its only right now. what happens after now?
