What is ur purpose of life?

Hey there! I am a 17yr old girl.I am currently in 12th grade.I have no idea what I want from life and what all I need to achieve.I want to tavel a lot and to enjoy my life to the fullest.I haven't figured out about which career I want to pursue and that's the main thing draining me.soon I will be graduated from my school and I should choose a course and a college ,of which I am uncertain of.

I don't want to look back and regret that I wasted my entire life and to deal with thoughts like I haven't done anything beautiful or I haven't left any special place in anyone's heart.

Have u all had similar thoughts or how u delat with the confusions of uncertainty of life ( My eng is not good enough so please excuse that and feel free to reply)
