Here are the three Core values, I beleive
When everything around us is changing, when the world is difficult to understand ,our core values will always be there for us. I believe in patience ,yes I agree Patience is bitter but I also agree its fruit is sweet.
Our attitude matters in every part of the life. We need to have a positive attitude in dealing with new challenges. Also,
One need to have positive attitude while waiting.
Perseverance, major character trait for one to be successful in life here I like to add my favorite quote "The only guarantee for failure is to stop trying".
Situations in our lives keep on changing constantly and quite unexpectedly too. The ability to accept what you control and what you can't control is required in life.
