“Things change, and not always for the better.”
“Any change, even a change for the better is always accompanied by drawbacks and discomforts.”
“If you want things to change, you must change. If you want things to get better, you must get better.”
“I cannot say whether things will get better if we change; what I can say is that they must change if they are to get better.”
“Things are always better in the morning.”
“Things do not grow better; they remain as they are. It is we who grow better, by the changes we make in ourselves.”
