€305k in one taxable account, thinking about going part time. Am I actually there yet?

I'm in the EU(38M) so there's no 401k, no Roth, no IRA, not even a UK ISA. No tax sheltered retirement wrapper at all. It's all just a plain taxable brokerage at IBKR. Makes the math cleaner but also scarier, since nothing is locked away, it's one account I could nuke any day I lose my mind. My numbers (I'm single): Net worth: ~€305k VWCE (FTSE All-World, accumulating): €230k AGGH (global bonds): €40k P2P: ~€10k Cash buffer: €25k, about a year of expenses No property, I rent a 1 bed at ~€750/mo
