It is being at the right place at the right time so it is all about perfect timing. Yr then, is a rune of perfection, the culmination of all one has learned over one’s journey, a symbol of skill and the proof and testing of that skill.
However, another meaning for Yr is the rune of the entrance to the Underworld and therefore in this format can be understood to be the 'the death rune'.... the Yew tree has long been associated with European graveyards. In this format, all is not what it appears to be ... on the surface the old situation is not changing ... but inside, just like the internals of the old yew tree decays and a new tree grows, then within a situation everything is different. This process will not become apparent until the bark of the old tree falls away.
