Sometimes we make the process more complicated than we need to. We will never make a journey of a thousand miles by fretting about how long it will take or how hard it will be. We make the journey by taking each day step by step and then repeating it again and again until we reach our destination.
It is very important to generate a good attitude, a good heart, as much as possible. From this, happiness in both the short term and the long term for both yourself and others will come.
