Our smartphones can be a blessing or a curse. We want to use our phones to improve our lives, not the other way around. For a lot of people the phone is controlling them instead of them controlling the phone.
Have you ever been to a dinner with someone you care about and in the middle of the conversation you took out your phone to have a look at it? I know I have… and I also have friends doing it to me so I know how rude it can be.
Whenever you are doing something important like having dinner with someone you care about or in the middle of something productive use the airplane mode. This switch of all the signals and you cannot get disturbed! If you don’t want to go all the way you can just put your phone on silence. Personally I would recommend you to start using airplane mode more in your life.
