Be careful not to judge other people’s capacity to do/withstand something. Not only are there different types of capacities/limits, such as mental, physical, or emotional capacities, but everyone is different in what their capacities are for each type. For example, you may be incredibly strong physically, but maybe you’re overburdened at home and your emotional capacity is very low.
Another thing to realize is our capacities are fluid, as they are constantly changing depending on what is going on in our lives. Maybe you just lost your job, your significant other decided to leave you (taking the dog too), and you were diagnosed with cancer. While your emotional capacity may normally be very high, you would probably be at the tipping point where even something very small which would normally not affect you makes you break down and cry.
These are just a couple of reasons why you should not judge others, but especially if you don’t have a good understanding of who they are and what their typical capacities/capabilities are. What you see from others is only a snapshot for where they are at any one particular time in their life.
Instead of judging others before you really get to know them, default to giving people the benefit of the doubt. They can be down one day, or even for a brief period in time, but after you’ve gotten to know them and their story, eventually you will have a better understanding of what their typical capacities are.
Just like anything else, we all have the ability to strengthen and improve each capacity. Are you working on improving yours? If you’re working with someone, or partnering with them, do you know if they are willing to work on improving theirs? You should not focus on where you (or others) are currently, but on where you (and they) are going based on their daily actions.
