Personal Finance? ? ?

Sprat is taking personal finance this semester in school.  He brought home a list of questions for his dad and I on our experience with money.  I honestly believe I could teach a young adult personal finance class.   I think I have made all the mistakes out there with money.  I am very proud to say I learned from my mistakes and did not make the same one twice.  
One of the questions asked, if I could share one important lesson about money what would it be?   With out a doubt it would be, never sign up for a credit card.  I signed up for my first card as a freshman in college.   I was working partime and had a $2, 500 credit limit with a 29% interest rate.  What was I thinking?  That is the point, I was not thinking.   I was too young to know better and my parents had never warned me of the evils of credit cards.  I do not think they ever imagined a company would give me credit.
I think I have shared this before, when talking about credit cards,  about all of the offers the hubbs and I received in a month.   I had over $352, 000 and my hubby had over $450, 000 in credit card offers.  This would have been in 1998 when the credit card companies sent out these types of offers every day.  We did not have that kind of money nor did we need that kind of credit for anything. 
You can live without credit cards but it takes patience, planning, and delayed gratification.  These are three things the kids of today are not being taught.  They are the now generation.  They want it now and do not care how they get it.  My kids are guilty of this too, so please do not think I am pointing fingers.   This has been an ongoing lesson for both of my boys.  We talk daily about saving for that all important pair of shoes they absolutely must have or the game that they cannot live without.  If it is over and above what they NEED for school then they pay for it themselves.  Both the boys have bought their own shoes with their own money (birthday or commission) if it was something that was a want and not a need.  Yes, I am that mom.
