Practical advice at your age is to study and equip yourself for the various challenges of life as well as to express your deepest truth. It means learning a lot of things and then zeroing in on the one you feel is closest to your heart. The next important thing is to be financially independent and explore life and world while nurturing your higher aspiration. These are the two purusarthas of Indian thought.
Yes leaving it in the Mother’s hands is fine but just make sure it is not an escape from effort.
