What is the adventure?

Why do I have to consider every little thing before I get started? 'cos if i don't i sincerely believe i will have fucked something up. Then again, considering takes most of the time that, as a matter of fact, is limited. But when I get started without considering I'm lost. So maybe living stands for being lost and finding your way. And this is the adventure everyone is talking about - the adventure of life. But they are all afraid of getting lost because they believe it's near impossible to find their way again. So people, what is the adventure you're talking about?
