There are two types of relationships between money and time. To differentiate the two, the key is you.
One, you pay your time as currency for stipend. The value per hour is constant. It’s like you pay your time to buy money. You basically have no role in it.
Second, you spend some money for time, then with the time you buy, you are making more money. Here, you are a converter. The value of hour at your hand is no longer constant, you can make it miracle.
