At school did you sense subtle pressure to do Maths at A-level (or French, or Art or whatever)?
Did you choose the university course that others would approve of, rather than the course that you would have been really passionate about?
In your working life have you taken roles that would build towards your ideal career path rather than following the slightly more fun & exciting path?
There’s nothing wrong with that, as it probably (hopefully) led to a secure life for you & your family.
There’s nothing wrong with those previous choices, so long as you are going to allow yourself, at some point, to follow your passion.
What is your unrealised passion?
