Your personal Facebook profile is like your name tag on that playground. It shows who you are, lets you share pictures, talk to friends, and play games with people you know. You can post photos, stories, and thoughts, and your friends can like and comment on them. It is mostly for fun, staying in touch with family, and chatting with friends, not for serious work stuff.
The advantage of changing your username is that you can pick a name that is easier to remember. If your old username was long or confusing, a simple one helps friends find you faster and share your profile easily. Another advantage is that it can match your real name or personal brand better, which feels nicer and more personal.
Another important advantage is privacy control. If your old username had personal details like your full name or birth year, changing it can help you feel safer online. It also gives you a fresh start if you made the username a long time ago and no longer like it.
the major disadvantage is that old links to your profile stop working. If you shared your profile link with friends, on WhatsApp, or on other websites, those links will no longer open your profile. This can confuse people who try to find you using the old link.
Another disadvantage is that you cannot change your username again quickly. Facebook has rules and usually makes you wait before changing it again. If you choose a new username in a hurry and later regret it, you may be stuck with it for some time.
