As a self-employed entrepreneur, you can be engaged in a
small business activity at any age.
If you're still at school though, you should make sure that
your business doesn't interfere with your school work -
it's best not to be involved in business full time.
If you intend to run your business full time and you're
under fifteen, you must ask the Minister of Education in
your state or territory for permission to do so.
Running a business requires many skills and a lot of
experience and knowledge. To be a smart entrepreneur and a
good manager, you should learn as much as you can before
you embark on any business project.
There are many small business projects that young people
can be involved in at school, after school and during
school holidays. These give you the sort of experience you
need to start up your own small business in the future and
be successful doing so.
