So, let’s meet live on Saturday in a place I’ve never been to before.

The invitation has been sent to my supporters. If you are a supporter and didn’t receive the email, the walk begins at 7 pm Kyiv time: https://t.co/L8n2Vi7wMa

Fingers crossed my trip happens 😉

For my supporters who couldn’t join today’s live walk or would like to see a little more of Lutsk (a city in northwestern Ukraine), I’ve made a short video.

You can watch it here:

Sunday Letter from Ukraine. Pysanky Through Time

https://t.co/oD8P89ba6x

[Yaroslava @strategywoman]

Older than it seems.

In Ukraine, pysanky go back centuries.
They changed form, but did not disappear.

I wrote more about it in my latest Sunday Letter.

[Yaroslava @strategywoman]

I’m able to show Ukraine because of my supporters.
Thank you.

Lviv was under attack today.

In this city, Olena Kulchytska worked.

During her life (1877-1967), she preserved Ukrainian culture from being erased.

This culture is under attack again.

[Yaroslava @strategywoman]

I’m having a warcoffee.

It was a day of drone attacks.
Kyiv was not damaged.
But other cities were: Lviv, Vinnytsia, Ivano-Frankivsk.

There are casualties, wounded and damage.
💔

[Yaroslava @strategywoman]

After planning another short trip not far from Kyiv,
I felt that something needed to change.

I want to show Ukraine differently.

Today, I begin Hidden Ukraine

[Yaroslava @strategywoman]

Ukraine is often reduced to headlines about war.
I write about the whole picture.

My new Sunday Letter is about Masnytsia (the week before Lent) with videos and photos from yesterday’s festival

(Sorry for the confusion with invitations 😬 My head is full of tulips today.)

[Yaroslava @strategywoman]

A quick reminder: a live talk from Kyiv with my supporters starts in 30 minutes (10 pm Kyiv time).

I’ll answer questions in real time and will be glad to welcome you.

They are not a broken generation.

My new Sunday Letter is about Ukrainian children and the strength they are growing into.

Greetings from Kyiv.

Just checking in.
Nothing new, electricity and heating remain difficult here.
The frost doesn’t leave us, -16 °C now.

Hope your Monday is (or was) kind, and that you’re grateful for everything you have.

[Yaroslava @strategywoman]

Greetings from Kyiv,
that survived another russian night attack.

2,600 high-rise buildings are now without heating
(in addition to the 1,100 that will remain without it this season).
We still have some.

In a few days, frosts will return.
I don’t know how to make the world listen.

[Yaroslava @strategywoman]

Kyiv.
After midnight.
Electricity is back for a short, dear while.
I’ve published new excerpts from my diary.
Many of you got them by email –
