Explanation:
I think you should realize ASAP how futile it is to be disheartened by this fact and regret it (beat yourself up for it).
You think you’ve wasted your day. You’ve told yourself that you’ve wasted it.
Objectively nothing like that happened. You’ve lived through it. That’s an objective fact (without your or anybody else’s judgment).
What you make out of it is thus everything as far as your feelings about this single day are concerned.
