This is so true. The 'tired' that requires peace is the type of tiredness that I experienced on a daily basis for the past decade, before I retired. Weariness of soul is another way of describing the tiredness. There is no such thing as peace in modern workplaces, no such thing as respect or understanding for those who enjoy working alone and for those who tend toward introversion. No, you must be on all the time, available all the time, willing to attend pointless meetings ad nauseam and willing to be a team player. If you don't like any of these, you won't thrive. There is no longer any support for differences between people; we must all be the same, like the same things, feel the same way, and agree on specific issues even when we don't agree. Honesty is not valued; conformity is. Leaders don't want to hear the truth, they just want you to agree with what they want and decide. Many modern workplaces are just unhealthy places to be, causing anxiety, distress and negativity. They wear you down.
In 2016 I was blessed with a considerably-sized garden plot in a local allotment garden. It has given me peace and the chance to reflect on different things while I do the work that the garden requires. There is nothing else like it for the chance to know happiness and true peace.
