Having willingness and interest is very important for a good career.
Although "My parents" are right about continuing to study, My steps that I would suggest to help resolve the issue:
suggest making a small company for a start. As A young entrepreneur, I
would suggest my sister to use her creative ideas and make the items
(pots and vases) and sell the on weekends.
So on weekdays she can continue with her studies
This same question was there in Brainly before
anyways I hope this helps :)
