We talk about trust, friends, and relationships. Think about the love/crush at school/colleges. All the dreams we made together. How many of it stays to reality?
We human species are a slave to our thoughts. It’s tough to move past those promises and whatnot. When you were kids, you were different: you were more innocent and break free. As you grew up, society took over you and your consciousness.
Accepting what is present and learning from the past will cement your life for a better future. Moving on is tough, so is the cure for cancer and getting past the death of your family members. The day you accept it, life gets less painful.
