What you liked, the people you were drawn to, attitudes - everything, does a complete turn around when age 24 hits you. It happens to everybody, whether they consciously realize it or not. The REAL YOU will never develop. Next, I'd begin my life. I'd begin to DO the things that I've dreamed of doing, since I began dreaming.
Freedom is a wonderful thing.
To be able to come and go as you want without having to 'ask permission' is a great feeling. But it comes with a responsibility for yourself. Always remember that for every action you do, there is a result - so be a responsible person for yourself. Be careful who you befriend and where you hang out. Once you are married - it's like still being a little kid under your parents authority, having to 'ask permission' to do anything.
