Be a university of life student
Learning at school is important, but there are some things that might be better developed through lived experience, or in situation that can only happen outside a traditional classroom
Where to start
Think about what you want to achieve, and what you might need to learn to do this. Is this how to rent or buy a house? Or drive a car? Or start your own business?
Talk to someone that might have achieved the thing you want to do, who might be able to help you on this journey.
Research into the steps you might need to take to learn what you want to do. This might involve attending a workshop, doing a course, or discovering a new process.
