* Get PhD. Everyone should know at least something inside and out and have contributed to that little a bump to the human knowledge. At minimum stay in school as long as you possibly can. * Take a year off before you decide to be a corporate employee or start a corporation of yours. Go see world. There has never been time like these to experience literally 100s of cultures that has evolved during past 1000s of years. If you postpone this to later age, most likely it's not going to happen because you will have job with limited vacation or partner who has different preferences or kids who can't travel safely to wild places. You are living Marco Polo's dream. Don't waste it. * If and when you decide to seek employment, give money the least priority. A lot of young people are fixated on money in initial years either because they want to feel safe or want to prove themselves. This puts them on path to become corporate slaves that you see all around you and get disgusted. A lot of non-profits, pure science/art organizations and academic jobs has higher possibility to unlock your potential and give you enjoyment and satisfaction than initially higher paying jobs in big corporations and likes of wall street. * When you are young (which I mean by less than 30 years old), involve in as many physical activities as possible. Mountaineering, rock climbing, kayaking, hiking, backpacking, swimming, marathons... Pick an activity, set a yearly goal and train for it. For example, swim a mile in open ocean or run a marathon or climb a 14000 footer or do your first 5.10 rock climb. Subscribe to local groups that does these so you have motivation. All these are going to get much harder to pick up as you age. If you had started training for at younger age, you would continue to enjoy it in your 40s, 50s and sometime even in 60s. There is absolutely nothing more important than to be physically fit in your old age and you likely won't get there unless you are active through your life. * Make physical things! Have something non-trivial to show for each year that you made by your own hands. This would require to learn electronics, carpentry, machine tools, automobile engineering, plumbing, sewing, cooking and so on. Pick one of these skills, enroll in to real course at community/professional colleges and set a target to make something. These are skills takes years to perfect and unless you start at early age, chances are that you are not going to master it. * Don't rush to get married. A lot of times you will find a person who you think is perfect for you. You might even have anxiety to lose her/him. Take as much time as you possibly can without getting married. This is essentially to get to know person and them to know you. Once you get married, life is very different. You will take less risk and you will have far less time for anything else and your choices will be governed by mutual agreements instead of your own will. It's not a waste of time but it's different. If one you or both decides you have children, your life will change even more dramatically again. With even less risk taking, even less hard core exploration and even less time for anything else. Having children is rewarding but while you are young, do things and invest your time in things you can't do later.
