Amount of farms owned by anyone in my family = zero, then and now.
Saved up/earned my own money to fund purchase of farm = true, every penny.
Amount of money given to me from family members = zero...in fact, my parents took money from me while I still lived at home and I was paying for virtually everything I had from 16 years old on.
Wife = one, who worked her way through college as well, no debt when graduated. Me...I owed some, but paid it back years ago.
Kids = two. Both of whom also graduated with high honors from college and had zero debt when done, as they used savings, worked and earned scholarships too. As parents, we did help them some, but in the main, they paid for their own way.
Seriously, it is possible to do everything you mentioned above, bolded, BUT...and here is where people differ...you probably cannot do all of the above AND combinations of the following...
Drive brand new cars/trucks, live in $350k on up houses, spend significant funds on: booze, girls, clothes, shoes, CELL FREAKING PHONES, video games, motorcycles, expensive boats, fancy furniture, expensive vacations, high end home electronics, etc, etc, etc. (BTW, I am not saying that you do any of these things, as I do not know you. But I do know multiple people that do a combination of these things and then complain that they have "no money".)
Choices. Drive. Hard work. It can be done.
