The definition of 18 is a milestone in life. It marks the beginning of adulthood and all the responsibilities that come with it. At this age, one can legally vote, purchase alcohol and tobacco products, enter into contracts without parental consent or permission from any other legal guardian, join the military and be held accountable for their actions in criminal court as an adult.
18 is also often seen as a time to begin exploring independence by making decisions on your own such as attending college or university away from home or taking on full-time employment outside of school hours.
In many countries around the world turning eighteen also means being able to obtain a driver’s license which gives you even more freedom to explore new opportunities at your own pace while still having some form of safety net if things don’t go according to plan – something that was not available when you were younger!
Turning eighteen should be celebrated because it signifies both growth and maturity; two qualities needed for success in life no matter what path you choose!
Whether its academic pursuits like higher education or career focused endeavors such as starting up your own business venture – reaching this age will give you access to resources previously unavailable before now so take advantage of them wisely!
