Without a doubt there are probably hundreds of ways to find your own success. As someone raised middle class, I don't see a huge problem with stock piling cash. If that feels safer, then I say do it! But if you're sometime who's interested in making your money work for you, you'll definitely have to work to change your deep seated beliefs.
Thank you for commenting and sharing your experiences. I find it interesting that someone with investment savvy parents would prefer to save, but I'm sure there are some experiences that solidified her psychological beliefs around money.
