Make Time For Things That Make You Happy
We're programmed to think that you always have to be 'busy' in order to be productive.
Being busy won't necessarily make you happy.
It may instead lead you to self-delusion.

Everybody needs down time.
Don't work up until exhaustion. Work smarter.
Make the time to put your phone down and reflect.
Catch up with your own thoughts without the guilt of needing to be 'busy'.

Don't let the excuse of being time poor detach you from your true self.
Tell that friend you can't meet them for coffee. Tell your boss you can't cover that extra shift.
Tell them you're busy.
