I have not been that wise. Health I have taken for granted. Love I have demanded, perhaps too much and too often. As for money, I have only realized its true worth when I didn't have it.

Basically, this quote is saying that I haven’t been very wise. I have taken my health for granted, thinking that it will stay the same without me having to do anything to look after it. I have expected too much from love, perhaps asking for more than I should from relationships. Finally, I didn’t realize how important having money was until I didn’t have it.
