Today's Bible time was in John 17, especially verse 4:
I have finished the work you gave me to do.
Young person, please do not defraud God on this matter. He has created you for a work that only you can do. Do not limit him. Do not put him in a box. Do everything you can to find out what his will for your life is so that, with Jesus, when you come to the end of your earthly existence, you can say two things:
Father, I knew what you wanted me to do with my life, and, by your grace, I have finished it.
There can be no greater blessing.
