I'm 30, I am trying to achieve what the other person described. I'm not there yet, but I feel like I might be in 8-36 months timeframe. Ask me then, you'll get at least one more data point that's not just survivorship bias.
At 30 you have nothing to lose or even if you do you have decades ahead to turn things around. Despite what I said I wish you and other young people luck, enjoy your life doing what you love before you get old and grumpy.
