Private Foundation / Family Investing Advice Sought for

Hello,

My family has 15,000 mineral acres in south texas as well as 5,000 surface acres. The last three generations have lived off of oil & gas well royalties and it is all going to **** if I am being honest. Selling land left and right, grandparents did not invest, etc.

How can I turn this around? Create my own foundation with the 200-300 acres I will inherit in 20 yrs? Convince my dads generation to allow me to inherit a few acres right now and I can maybe try to multiply that into more capital and create my own foundation?

I am at a loss for words. Any help and advice is appreciated.

Thank you.
