Quite the irony that the thread started with reminiscing about life and purpose and needing time and valuing relationships and you guys go into the "need to make more money" spiel.
Here comes a secret: It will never be enough for you. It's not the money that counts. It's the ratio of income versus expenses, if anything. And if you grow one and don't stop the other one from growing in unison, then you have gained nothing.
I know lots of people with 5x the income of me, but their expenses and lifestyle overcompensate, so they are much deeper into the hamster wheel than me.
I could retire any day (late 30s). I currently don't do it cause my work is fun and I like the people, and the more I keep going the higher my expenses could become if needed. But the finances don't keep me in my job. And if anything comes along that looks sustainably more fun I will quit in a heartbeat.
