It is important to work for others when first starting out, so glad to hear you are clear about first preparing yourself for a good job. You will both learn and earn on that job. Just make sure to live below your means so that you can save. Even before you're 100% clear on what you're saving for, save as much as you reasonably can anyway. Then when the right opportunity in real estate, agriculture, or whatever comes along, you'll be ready to take advantage of it immediately.
For 2 years after I started making quite a lot of money I still lived in a single room with no heat and no bathtub in someone's back yard. I could have afforded to live a very luxurious life, but I was saving for my future instead. It only took 2 years to set myself up on a path that 6 years later led to early retirement.
Thanks for the advise. I will keep that in mind when I get a job and start making money.
