The general rule for credit cards is they're only for emergencies.  I know I've used my credit cards wrong and it's a slippery slope that haunts you the rest of your life it seems like.

So, I started to search the vast reaches of the internet to see what I could find.  In my cyber travels I discovered a great article on CNBC that gives some great advice on what to stay away from when charging on your credit cards.

Here are 5 things you REALLY shouldn't use credit cards for:

1.  Big-ticket items you WANT but don't need.  That's the most obvious one.  You might WANT a new TV, but it's not worth going into debt for.  And a lot of stores will give you 0% financing for stuff like that.  And even then, it's only worth it if you have a plan to pay it off before the interest-free period expires.

2.  To pay off back taxes.  There are usually better options than using a credit card with a high interest rate.  If you sign up for a payment plan with the government, you can end up paying HALF a percent in interest instead of 20%.

3.  College tuition and books.  Student loans are a much better option because the interest rates are a lot lower.

4.  Medical bills.  Most doctors and hospitals will work with you to help pay them off.  Sometimes with no interest.

5.  To buy stocks or make other investments.  Buying stocks or things like Bitcoin with a credit card just isn't smart.  And even if you do turn a profit, the interest cuts into it.  So it's not worth the risk.
