I totally understand wanting to achieve FI independently. But I think it's pretty easy to be prideful in the process. America is obsessed with rags-to-riches tales, and will often not accept any story that is anything short of this. If you had any privilege at all, it will get called out by some clown.
When I was in high school, I had no car, but I remember once telling some friends that I wanted to save up for and buy one myself, to have that sense of accomplishment and independence. Ridiculous to me now. I've had friends who have been gifted with brand new cars by wealthy family members and did an incredible job taking care of those cars and really being responsible with such a blessing. To shun a gift in the name of autonomy seems just as ridiculous.
APowers mentioned above the desire to prove it can be done to peers, which I also completely understand (I'm about the same age). But if my FI were purchased for me tomorrow, I certainly wouldn't turn it down, though I may work a few more years just for the sense of accomplishment, which matters to me personally. Although, I think there are some fun non-paid ways I could also get that, so who knows? Besides, why would you need to prove anything to anybody else? What the path to FI has to prove is that gifts can be used wisely and not squandered. Most people on these forums could win the lottery and not end up like those people who blew it all and are now completely broke. The discipline, the mindset, is what lasts with you no matter what. People don't see it that way, they just want to see big numbers and know whether you actually "earned" that or not. Forget them.
