I learned that at a certain point, we must stop.


There are things that we need to stop doing or even thinking. We must accept the fact that things will not always stay the same. 


People change, so as their feelings.
Take note the irony, that the only constant thing n this world is CHANGE. 
Don't take things for granted, and learn to treasure them whether it's a thing or a person. No one knows what will happen.
