Binding Tooltip to Content of Textblock

I have a basic TextBlock

<TextBlock x:Name="myTextBlock" Text="textOfThisTextblock" ToolTip="..."/>

and I want to set the Tooltip to the exact same string as the Text of the TextBlock. How can I do that automatically?
So I don't wanna set it manually if I change the Text.

I tried

ToolTip="{Binding Path=myTextBlock.Text}"

but this didn't work.

use RelativeSource Self

<TextBlock x:Name="myTextBlock" 
           Text="textOfThisTextblock" 
           ToolTip="{Binding Path=Text, RelativeSource={RelativeSource Mode=Self}}"/>

or ElementName

<TextBlock x:Name="myTextBlock" 
           Text="textOfThisTextblock" 
           ToolTip="{Binding Path=Text, ElementName=myTextBlock}"/>

or you can do it for all TextBlocks using Style:

<Style TargetType="TextBlock">
   <Setter Property="ToolTip" 
           Value="{Binding Path=Text, RelativeSource={RelativeSource Mode=Self}}" />
</Style>
