Don't collect the stones

Never take someone for granted. Hold every person close to your heart because you might wake up one day and realize that you’ve lost a diamond while you were too busy collecting stones

It is not only about losing someone we love! It is about managing our time because we may not lose our beloved onces but for sure we will lose a precious time to spend with them. In our belief Islam Al Rasool el Kareend said

في الصحيحين من حديث عبد الله بن عمرو رضي الله عنهما
أن النبي صلى الله عليه وسلم قال
إن لربك عليك حقا، وإن لبدنك عليك حقا، وإن لأهلك عليك حقا، وإن لزوارك عليك حقا
فأعط كل ذي حق حقه

It is a clearly requested  to give everthing in our life the enough time, and not just to focus on one thing that we may think it is the most important thing in our life and at the end we may found ourselves spending long time with the wrong thing and losing to enjoy our time with right onces. It is not bad to focus or workhard on one thing but do everything in moderation.
