Everyone has been through the age of 21. Well, technically not for some Gen Y and even more so, Gen Z. When you turn 21 people has always considered you as a young adult. This is when you have reached the legal age of drinking, gambling, smoking etc. You can do whatever you want like what adults do without anybody controlling you. (Except for some insecure parents of course). When you turned 21 you definitely will have some thoughts on how you move on with life. Realistically, there are few things that you opt to know before your real life begins.
