oops, I'm sorry, but it's naive to think it's easy or sensible to go to university when you're older. Now that university involves hefty tuition fees it's always going to have an impact financially even if you are going to study part time.
The students most likely to drop out of university are mature students and those struggling financially.
I'm glad you're happy with your choices but it's wrong to tell people that you can be happy without money.
Of course it's relatively easy to be happy without money when you're young and healthy. It's a hell of a lot harder when you're older and have commitments.
And being without money when you're older has an impact on the rest of the family too for whom you are responsible. So your spouse may have to fund you through university, you may not be able to save up for your kids' university fees and you would certainly struggle to save for your pension.
I've said on other threads that people are not educated to take a long-term view of financial planning and I've seen too many people (esp. women) skrimping on food and heating because they have only the state pension to live on not to.
Obviously some people are not in a position to save etc and obviously life choices should not be dictated by money alone and certainly not earning power but certainly money should be a consideration unless you want to have your choices (and almost certainly your happiness) and probably those close to you also severely limited in later life.
