I'm guessing you don't have a mortgage? I imagine that is what most spend their money on. After this I would say groceries and holidays.

As a rule I give away a 10th of my income to my church and other good causes.

I imagine looking beyond yourself may bring you more joy, less of a feeling of emptiness.

I could probably count on one hand the meaningful tech I have bought. I would invest in people, experiences and then tech.
