YALL, don't get too discouraged yet! 26 is still quite young these days, and you have A TON of time to figure shit out.
I know plenty of people who are already in their early 30's, and they have no real idea of what they wanna do.... and it's ok! they are reasonable, (somewhat) responsible people who are just taking longer than their parents did to figure it all out!
You've heard "30 is the new 20?" Well, it's fucking true! Don't let that make you lazy, because you gotta get going sometime, but i would say just the fact that you've been bit by this "what-am-i-doing bug" is a good thing.
