It's true. We continue to regret something of the past or to make dreams about the future, without understanding that the only time when things can be done is the present.
We are always late for everything we could have done yesterday, but we didn't.
There are a lot of parties to go, a lot of trains to take, and sometimes we miss the winning ones.
But to regret is completely useless.
Moreover, if we lose our energy with regret, we will lose the parties that we could attend now.
So, if in the next months you don't want to ask again "Am I late?", stop whining and act now!
