Christmas Calender 11th hatch

I received a calender from my friend with positive things in it. It is a Positiivarit christmas calender. So here is what I found under the hatch number eleven:

"When you do, what you have to do at the time you have to do it, You will be once more able to what you want at the time you want to do it."

(translated by me. This one was a difficult one, as I almost used 'when' all the time.)
