Yap, that piece of advice about spending time came from Robert Kiyosaki though I did not read his book. I learned about the summary of the book and did no longer want to read it. Others still recommend doing so.
Some would regard the term "rich" as being greedy of money so they use "financial freedom." To me, it's the same banana and saba. You cannot be financially free if you are poor thus you have to be rich! 😊
