Ariana Grande admits she often feels ''overwhelmed'' by her success. The "Problem" hitmaker claims she is surprised by how quickly her career has taken off and is still adjusting to being famous, but hopes to be in the music industry for the rest of her life. She said: ''There is so much attention on me that there wasn't before. I've been so overwhelmed. But I would love to never stop.'' The 21-year-old singer insists she isn't a party girl and prefers to relax at the beach. She told PEOPLE magazine
: ''I love going to the beach really late at night. That is how I make sure I don't explode.'' Ariana, who is rumored to be dating Big Sean after splitting
from Jai Brooks, started practicing Kabbalah at an early age after being introduced to it by her brother, Frankie, and credits it for helping her to stay grounded. She said: ''I know it has become a 'thing,' but I've been doing it since I was 12. I love learning about the universe and how small we are in the scheme of things. It takes me out of my constant schedule of me, me, me.''
