I was introduced to a new financial Youtuber this week. Graham Stephan is a multi-millionaire familiar with the FIRE community. He has very thorough videos that breakdown not only his personal finances and how he follows the foundations of FI, but he also breaks down and analyzes other aspects of personal finance. In one recent video I watched, he broke down house hacking, rent hacking, travel hacking and the latte factor while not just repeating the same old ideas on personal finance blogs.
Check out his youtube video how he saves 99% of his income here: https://www.youtube.com/watch?v=mzL1fF6LC8Q
