If you have anxiety over money, for instance, you'd probably still have it, regardless of whether you had $15,000 in your bank account, or $15,000,000.
I’ve lost most of my money anxiety, but it took a lot of purposeful work inside myself to achieve that including years of daily meditation and intentional study of Buddhism. Before that my money anxiety was unbearable. It didn’t matter how little or how much I had, because it wasn’t about money in truth. It was a fear of losing control and other things like self worth and identity issues as a result of my earlier life. As I learned to let go of the self and my identity and live life as it is rather than what I’m afraid it might be I’ve lost my fears, not just about money but all of them. In my experience lack of money instigated my anxieties but once they started it didn’t matter how little or much I had.
That said it drove me to get more and more, and I enjoy having more than when I had none. But even if I lost it all I would be ok now.
