I don't know much, but what I know for sure is that there is no right time to do something.

We have no control over the timing of anything.

The only control we have is over our choice of saying yes or no to the door of opportunity when it opens and the action steps we take from there. 

I also know that the door usually opens at exactly what is perceived as the wrong time.

Of course it does, how else will the universe (or whatever you want to call it) know we are serious about what we are asking for?

Trust that the doors open when the time is right and that whatever your choice, yes or no, is also right.
