It's less about the destination and more about the journey. Sorry, that sounds so "dime store philosophy" but you are really in a great place.
There you are with a virtual world at your fingertips and you can do what ever YOU want. Any painter who has stared at a blank canvas knows how daunting that can be, (for me all that emptiness is very scary) but when you realize it's just about your choice it's really Freedom. Don't like what you chose? Choose again. And keep asking yourself "What do I want?" It's your Universe.

This is sounding kind of preachy over-the-top but you're in a perfectly normal place now, I'm just trying to nudge you into the next space that comes after it. cheers
