Karma is not the universe's revenge, it is the reflection of your actions. All things that come from you come back to you. So you don't have to worry about what you receive, worry about what you give.
Please remember to check in on your strong friend, you busy friend, your happy friend... or your seems to handle everything well" friend.
Sometimes making people forget about their worries or what comes next- that’s the most important thing you can do for someone!
