Managing expectations

Expectation its something we all have about something all the time. And not all the times, but most of them, i actually hate to build expectations about something. I really don't want to seem negative right from the first few blog posts but still.. Don't you hate when a friend makes a big hype over some movie and when you finally watch it you think something like "Those were the worst 2 and a half wasted hours in my entire adult life." and then you feel like you want to go straight to your friend and ask for the movie ticket refund. I look to expectations like when you are in the 30 feet pool plank and there's a thick fog between you and the pool. Sometimes you might fall on the water, and its the most amassing feeling, but most of the times the pool is either low on water or completely empty and then you break your neck... figuratively speaking that is. Most of the times i rather build lower expectations (yeah kinda like the MadTV sketches) and be amazed when whatever it is actually happens. And you can see this happening in almost everything. Although i'm a tech guy, there's some things i would love to know about psychology and human nature... Being this one of them.
