Life is short. You will never know whether you would celebrate your next birthday. Appreciate people and their efforts.
Show love. You will never know when is their last day. It might be yours as well.
60% of people have regrets about not being able to deliver what's in their heart to their loved ones, after they passed away.
As much as you cannot get time back, and hence, you run behind time. Similarly, you cannot get love back, and hence, run behind it as well. There is nothing wrong in stopping your ego for a second and letting other person to you.
Think before you speak. Think before you say something in an argument. You both are responsible for a fight. It's you vs the problem. Try to solve the problem instead of proving they are wrong.
Keep promises. "Make your partner happy". What more do you want? Treat them right. It all comes down to the end as "Give Love Take Love" and "Give Respect Take Respect".
