Dear Polish friends,

The support that you have provided for Ukrainians in the most dire circumstances is invaluable.

We are very grateful for it - saying this as someone whose life was also saved by the Polish doctors last year.

The current situation is not pleasant, but it’ll pass.

Sending lots of love ❤️

[Illia Ponomarenko 🇺🇦 @IAPonomarenko]

Dear Polish friends, I want you to always remember that despite regular quarrels, big and small, between our countries (actually a normal thing in international relations), Poland is and always will be our closest neighbour and best friend in need.
We Ukrainians will never forget what you did for us in this war - nothing can change this.
Everyday problems come and go, friends remain friends.
🇺🇦🤝🇵🇱

Make money by making concentrated bets on yourself.

Invest money by betting on people you would work with, running businesses that you could run.

We opened a temporary sea export corridor. We’re working to preserve land routes. Alarmingly, some in Europe play out solidarity in a political theater—turning grain into a thriller. They may seem to play their own roles. In fact they’re helping set the stage for a Moscow actor.

@piotrek_nowy Ciekaw jestem co masz na myśli mówiąc o mocno niedoskonałym produkcie?

Believe it or not but it’s possible to build a successful startup without taking an ice bath every morning you know.

@piotrek_nowy @rditrych Ciekawie czy mówienie o demografii nie wspominając o czynniku migracji nie jest oszustwem 😉

Creating something from nothing with a group of similarly motivated people is a peak life experience

I hope everyone gets to experience it at least once in their life
