Urban dictionary's definition of "that girl" is a "female in a social situation that purposefully draws attention to herself, usually resulting in being that girl that is disliked."
Girls are known for tearing each other down rather than building each other up. It's almost a stereotype that girls are automatically crazy jealous of each other or just not friendly. Living in a society like this, rather than being "that girl" that is trying to draw negative attention to herself, be "that girl" that draws positive attention to herself.
Don't be the girl who is never happy for anyone else. Instead, be that girl that is always happy for others.
When someone is happy with something or someone in their life, who are you to tell them they can't be? Sure, you can disagree with some of their decisions that they are making, but that doesn't mean you should try to take their happiness away from them. If someone is happy, let them. No one wants to be around that girl who is just never happy for anyone. If you're happy for others, they will be happy for you. Being happy for other people will just radiate happiness into your life and who doesn't want that?
Don't be that girl that can't let go of the past. Instead, be that girl that accepts her past and moves on.
Let me start off by saying, that we have all gone through hardships. Some people's hardships are harder than others and it is unfortunate. However, if you live in the past, you will never move on to your future. Like the saying goes, "You can't start the next chapter of your life if you keep re-reading your last one." Which I can agree with 100 percent. Stop dwelling on all the negative experiences in your life and focus on better things that are ahead. It's okay to grief in different ways. Everyone needs to be able to express themselves, but in a healthy manner. Don't unintentionally bring yourself down by constantly trying to relive your dark past.
Don't be that girl that tries to please everyone. Instead, be that girl that pleases herself.
This is something that I struggle with because I often put other's before myself. Sometimes it's hard to put yourself first, but it's necessary. You will never please everyone, so make yourself happy. Be proud of your accomplishments and don't let the people around you stop you from chasing after what you want.
Whichever girl you choose to be, choose with confidence in that choice. You deserve to wake up every day and either be happy or the opposite with the choice you have made, so choose wisely.
