Grow up to and grow up into

Hi teachers~

I am having a hard time figuring out the difference between these two expressions.

1. grow up to be/do something

To talk about what a child will be like in the future, use the phrase "grow up to be ___".

Ex) I want to grow up to be a comedian.

2. grow (up) into somethingTo become a particular type of person as one ages and matures. Ex) Wow, Julie has really grown up into a very poised young woman. Thanks in advance~~~
