This is an easy one - go for it! With your age, experience and accessibility to support from friends and family I think the upside far outweighs the downside.

This is an easy one - go for it! With your age, experience and accessibility to support from friends and family I think the upside far outweighs the downside. You haven’t mentioned any financial commitments (loans, dependants, filial support, etc) so presumably you have none. You will probably regret not going for it more than sticking with something you hate.
