Feeling lost for greatness...

Lately I feel lost, more lost than I've ever felt in my life. I have always felt I was destined for greatness, doing amazing things in this world that actually make a difference. But at the moment I can't seem to figure out how I will get there. People tell me right now I should be excited because I have a chance to look around and figure it all out without any problems. But instead I feel completely lost. Without direction, without ambitions. It is the most awkward feeling I've ever felt in my life. Everything I've ever read or known tells you to decide on your goals and from there take the steps to get there. Fine and good when you know what your goals are, but what do you do when you have NO IDEA what your goals are. How do you proceed, how to you figure out the steps to get there? Where on earth do you start? Career wise right now I've just been applying for literally ANYTHING to get me going. I've lost my passion for what I do currently, and I also know it isn't fitting for having a family and knowing that will be happening in a few years I need to find something that works for that situation. But I'm feeling lost, and completely clueless and I'm not sure where to go from here. Hopefully in the next few weeks I can figure it out! Wish me luck!
