Experiences of thoughts, feelings, and actions, even when pleasurable, usually require some energy, involve some stress, and arise in response to stressful situations: talking or playing music to fill socially awkward silences or to avoid unpleasant feelings; eating, sleeping, etc. to satiate biological needs or seek pleasure; working to make a living, pay for education, buy entertainments, etc.; feeling anxiety from social or natural pressures; feeling depression from hopelessness or weariness; and so on.
Though one can try to avoid or minimize stressful situations, one can also minimize stress by refusing to create more thoughts, feelings, or actions than necessary. For example, if one must, one can speak only softly and in an emotionally monotone way, drive or walk as slowly and calmly as possible, eat simple foods without seasoning, do other biological things in a routine way as little as necessary to stay healthy, and minimize expenses so that you can minimize how much you have to work. If one embraces them, peace and quiet can be perhaps the purest forms of happiness.
