List of things you should know how to do before you turn 30--life skills, practical skills and social skills that you can and should master by the time you leave your 20s behind you. These are things everyone should know and should have figured out before they become full-blown adults and have families of their own.
Many of the items on this list are skills every man should have and that every woman should know in order to feel confident and self-reliant. The more life skills you have, the easier it is to take chances and strive for greatness. Some skills people should have are simply practical--like knowing how to swim, build a fire or drive a manual transmission. These skills are relatively easy to learn and are based on facts you should know. Other of the life-skills on this list are more subtle and need to be learned over time--how to tell a good story, negotiate and set a longterm goal and meet it are examples of these skills.
Since we all have different priorities in life and we all value skill sets differently, this list is an open list where users can add what they think everybody should know before 30 and vote for what they think.
Be Comfortable Alone
For you, being alone no longer = being lonely. You have your own interest and you do not despair if you occasionally roll solo.
Know Cooking Basics
Scramble an egg, bake a cake, steam vegetables... you may not be asked to compete on the next season of Top Chef, but you can make a simple meal for yourself without resorting to take out or calling your mother for help.
Handle Your Own Finances
You have your own checking account and maybe even a savings account and maybe even a 401(k) or an IRA. You may still be saddled with student debt, but you at least have some foreseeable financial stability.
Get Out of a Bad Relationship
People who make you feel bad about yourself, are condescending, annoying, rude... you've purposefully cut them out of your life to make room for more healthy relationships.
