If you are important, the person will make time for you no matter

how busy she or he is.

There is no need to ask whether you are important or whether she or he misses you because his or her actions will let you know.

Stay in touch with those who are friends, but first know the meaning of what being a friend is.

Don't ask the person to stay because if you two are meant for each other, no obstacles will come between you two. 

Life is too short to worry what cannot be changed, just focus on what you can change.

Treasure each day as if it was your last day because we don't know what is waiting for us tomorrow.

Don't waste your time on what cannot be yours because you will miss what's waiting for you.
