It depends. If I can afford life, I wouldn’t work 70 hours a week. I would give up the extra money from a second job. Especially, if I was feeling physically exhausted. Exhaustion shortens my life I think. Higher stress levels, I catch colds more, I just hate it.
In other cases I will give up a little time to save money, I weigh the cost benefit ratio. If I do something myself, like say mow the lawn, is it worth saving paying someone? Or, driving farther to buy something, because I will save money? It just depends on the amount of free time I have to go out of my way.
Unfortunately, money is important in our society. My advice is save as much as you can, and don’t spend on things like alcohol, cigarettes, manicures, many meals out, and Starbucks coffee. When you get a windfall, sock it away in the bank, don’t splurge on something. A windfall can be getting your tax refund. I know so many people who live check to check who take that money and spend it on something big. Don’t do it if you are in that situation. Once your savings account grows, you have more freedom. Freedom partly means more control over your time, but also more freedom to afford what you need and want.
I want to add avoid credit card debt at all costs, if you can. Pay your credit card every month in full. Allowing a balance to carry over means you will be working harder, longer, to pay for whatever you bought. A $50 item quickly becomes $90. Don’t do it.
