We all have different thresholds for all kinds of events, emotions, and endeavors in life. For example, I have a brother-in-law who seems to be unstoppable. In an understated manner, he just keeps going no matter the physical feat in front of him. His threshold for athletic endeavors is great. My family's thresholds for the cold ocean waters of Cape Cod vary greatly--some hop right into those icy waters while others avoid the water until they reach unusually warm temperatures. Thresholds for temperature whether it's water, air, inside or outside always vary. Our thresholds for good and bad news vary too--some can handle a lot while others don't want to deal with the bad news at all. Our individual thresholds for life's events, emotions, and endeavors vary from time to time dependent upon all kinds of external and internal factors. Bottom line, thresholds differ.
It's good to understand how your threshold may differ from others as that helps you to navigate people, places and ideas. For example some of us have high thresholds for social interactions while others need much more quiet and alone time. So if you're gathering with those who prefer more alone time, you'll likely schedule that time in when you're spending a lot of time together whereas when you're with a social bunch, you may plan more parties throughout your times together.
When you stretch someone's thresholds, they'll let you know in subtle and overt ways. Be on the lookout for that, and use that as a guide for the situation at hand and future times together too. The more you understand your own thresholds, the better you're able to communicate that to others which leads to greater peace and harmony in any endeavor. And knowing your own thresholds gives you a chance to decide to live within those boundaries or perhaps modify or enrich those boundaries in new and different ways.
Thresholds are a valuable concept in life, one that it's wise to consider with regard to any relationship, situation or endeavor. Onward.
