Celebrities are often surrounded by their famous acquaintances and people in their team who eventually become their friends. Some stars choose to stay close to the friends they had before the fame, and they often serve as a reminder to stay true to themselves and not let the success or exposure change them.

Selena Gomez said knowing the difference between real friends and fake friends was the biggest lesson she learned from 2016 and it is why she has been seen spending more time with her friends who are not famous recently.

"I would say, the biggest lesson that I've been learning since 2016 would definitely be awareness," she said on Instagram Live.

"I think it's really important to be aware of like, the people that you're surrounding yourself with, the people that are purposefully the ones you are spending time with. We go to dinner sometimes with friends, and sometimes we'll go to dinner and we'll leave and we'll think, 'That was such a pointless dinner. What did I learn from it? What will I gain from it? What was the point of it?' And then other nights we'll sit at the table for five hours with friends…[discussing] where you are in life. Like where we are, we're constantly checking in with each other. Like 'hey, are you good? Are you good?'"

She is quite right! Being conscious of who you spend time with can have a tremendous impact in your life.
