Let's be a bit more realistic, I won 1 000 000 €. I would donate most of the stuff:

• Transfer 500k € to the National Bank of Ukraine;
• Transfer 70k € to nonprofits in my city;
• 30k € goes to spread the message of FOSS and Linux to Lithuania. That includes:
  • Establishing and maintaining a nation-wide open-source social network, primarily targeted for IT
  • Funding to FOSS projects in Lithuania (I don't know any ATM, though)
• 100k € goes to global IT non-profits, such as:
  • Wikipedia;
  • Lemmy and the Fediverse;
  • The Linux Foundation;
  • et cetera.

I am left with around 300k € that I'd use for myself.

Non-capital (leisure and hobby) (40k €):

• I'd like to have some free time/make my close friends happy, so ~10k € for that.
• Also, I'd like to travel to Japan, meet ZUN, have some alcohol-free beer with him. 10k € for that.
• 10k € for travelling (leisure) across Europe (incl. attending FOSDEM).
• Knowing myself, I'd really have some mad and stupid ideas appearing in my head, 10k € for that.

Capital/investing (260k €):

• I'd definitely have to buy an accomodation in Kaunas or Vilnius (I hope it's not Vilnius) if I'd like to continue my career in IT, so 100k € for that.
• Education (in a period of 3 years) (10k €):
  • LFCS/LFCE courses
  • Advanced mathematics and algorithms courses
  • Professional soft skills training
• 10k € is reserved for a black day, unused.
• 15k € of non-profit network infrastructure (hosting FOSS projects) (incl. maintenance for 4 years)
• 15k to have an individual for-profit business.
• Distributed investing (90k €, incl. investor costs)
• 20k is another buffer money for household expenses.
