The way I started approaching magick (and for that matter any spiritual discipline) is simply assume that it has worked and let the results BE.
It’s hard to do so especially when you have been trying for so long. I know.
I’m very similarly in your situation:
—almost 50 in few months
—have been looking for jobs for almost 1.5 years (semi-successfully)
—here I describe my job search magickal journey
I don’t, for a moment, think that your magick has not worked. Though there are times we need to let the magick breathe and I think you may have reached that stage. What I mean by “letting magick breathe” is taking a break from magick, short or long. In your case, from wealth magick specifically.
I might reach that stage eventually or not but I take breaks from the wealth magick with other magick (protection magick which I’m doing currently and soon use Angels of Alchemy to work on myself.)
I might just take a break from magick in general for a few months. So far, it has given a certain discipline that I have lacking and I look forward to it daily.
Edit: I forgot to mention, I realized that I have blockages regarding wealth and career: ancestral, cultural, familial, psychological, emotional, and whatnot. So working on myself is a must for me.
Hope things will start working out for you and with you.
