Do things in proper sequence....graduate HS, go to tech schools (free in the military, but don't sign up without a guarantee of the school), or Jr. College, or college, get a job, get married, and THEN have kids (keeps your parents involved in your life and willing to help).....
Buy NOTHING on credit that you don't absolutely need. Until you have a good job and benefits (private or your employers), you can't afford kids. If you are lucky enough to have a spouse that works, live on the higher of the 2 incomes and invest the rest. Home ownership is still a good long term investment, despite recent evidence to the contrary. Just don't buy more house than you need. Location is more important than actual size of the house.
Associate with like minded people, don't get into a spending competition with others or seek status based on THINGS.
something specific that has been addressed already....there is precious little on TV worth watching so why have cable or satellite?
Not counting news, there is only 1 hour a week that I watch, Big Bang Theory and 2 1/2 men...
There are some PBS shows I like, and they are available on the internet usually.
Where we live, an outdoor antenna works very well, and there is no monthly charge for that.
a little paranoia works wonders....our 2 kids watched us live carefully, and then saw that we had money to pay for their degrees. They have friends with student loans, and have expressed gratitude to us for paying their way. We will likely pay for our grandchildren to go to college.
BTW, a good way to motivate kids with respect to grades....our kids were capaple of A's, sothat was their benchmark. I paid them for A's, but not for B's, and they paid me for C's. Anything lower and all hell broke loose, never mind the money aspect. Being grounded until the next report card is cruel and unsual punishment, but you can't be prosecuted for it.
Our daughter and a friend started a free web site related to couponing, it has grown and expanded and they have been offered $1.5 million for it....
but they declined for now.
Our son teaches 8th grade science and is qualified for an admin job, just waiting for an asst. principal job to open up.
But the next generation will likely face more difficult challenges...so we are "investing" in them, motivating them to prepare for whatever comes.
All in all, it is a long term, generation to generation effort for the family, not just any one of us individually.
