I do at times and it is not at all uncommon, I left behind impatience. It is irrational to constantly be in a hurry, when you do not have anywhere to be and even when where you think you have to be is not very important. I say it is not uncommon because if you go out in the world all you see is people who think their time is more important than everyone else's and they put life and limb on the line to display just how important their time is. Time moves with or without our cooperation, time expects nothing of us in fact we may die without ever doing "anything" with our time. What we have is an opportunity a grand one to learn, but most will never do so. I am a firm believer that all things happen for a reason, maybe your anxiety at school was not unfounded, the idea that school will lead to self discovery is silly. It may lead to a job, maybe even your dream job, but it will not lead to self discovery. School more or less in my opinion hinders self discovery as you are forced to learn what others tell you that you must and then regurgitate it back to their liking or else fail and waste time and money. That is a lousy way to learn about anything, especially about ourselves and the world we live in. Don't rush life or doing anything, don't be anxious about time, because you nor anyone knows what tomorrow will bring it may very well bring our end without our permission and then all that worry and anxiety would have been in vein. Trust the way things turn out, do not be anxious or regretful, do what you have to do and be thankful, be patient and open minded and you may well land exactly where you are meant to be.
