work offline
Not everybody has the privilege to enjoy Internet flatrate. I am one of those who have to pay big bugs for each and every byte that’s been up- or downloaded.
I had to learn the hard way that it is always more beneficial for the purse to work offline and only eventually to sync with the cloud.
Telegram and WhatsApp luxury, that means being connected 24/7 is something not really necessary. Make ahead of time appointments, keep them faithfully. Respond to email promptly. That’s the proper and sober way to go through a healthy Internet diet.
