You know, to be honest, I'm never completely sure of anything - because who is? Is that such a terrible thing? In reality, most of us accept that not everything in life can be planned. We work with what we're given, hope for the best, do what makes us happy in the moment while still trying our best to attain what we want long-term. We realize that this is possible without having to completely predetermine every major point in our lives, and we do so without feeling any less accomplished than those who do the opposite. We go with the flow, if you will, and I personally see nothing wrong with this.
The point is, you really can stop calling me a child for living this way. In reality you're just a cynical asshole who can hardly keep a handle on anything he's involved in anyway, who believes he's some kind of psychologist, and who always feels the need to tell me how wrong I am in my own personal decisions for reasons I can't even fathom. Honestly, you could probably use to take a closer look at your own life before rebuking mine. Maybe if you could control your own emotions I would actually be able to trust you.
