you think you know...stuff

times in life you think you know stuff. you think you've got things figures out. well othertimes in life you realize that you didn't know much and you still don't. They say hindsight is 20/20. well of course someday you;ll look back on today and realize you didn't know much today. but we act like we know something. i suppose we do know somethings. at least er feign to know. that is our great defense isn't it. to act on what we think we know. do things based on how we know things at the time. hindsight may be 20/20 but i wonder how useful it is really. what's the use of seeing clearly if its already past. time to get a prescription for some foresight.
