DIY Urge Jar Question

I’ve decided to do the urge jar to stop spending money on stuff I don’t need. I love the idea of having “NO NEW STUFF” in my house. So I found a cute little spice jar in the cabinet and some jade beads that were for a craft project I never started. The jar is small enough to fit in my purse, too! The beads will fill the jar; the trouble is, there’s only 62 of them. Not 100. Just checking — is there anything special about having 100 beads, or does the brain hack mostly come from seeing the jar fill up as urges are allowed and not indulged in? Many thanks.
