Right now
There is no perfect time. There is no such thing as perfect timing. After the fact it may seem as such, and that is perfectly plausible, but for everything else, there is no such thing as perfect timing. There’s always one reason or another that means the timing is not ideal. Often these reasons we conjure up ourselves as a way of excusing inaction. Yet if there is no such thing as perfect timing, there’s no excuse not to do the thing right now.
In other words, perfect timing is right now.
