I try to spend around $600&#x2F;mth on food, gas, drinks and other entertainment. This works out to roughly $20&#x2F;day. I keep a running tally in my head day to day on what I&#x27;ve spent and try to stay around $20&#x2F;day.<p>This is not a great tracking method, but just having the idea of $20&#x2F;day in the back of my head curbs my spending a great deal.
