integrity is doing what we believe is right to do at the time
I taught at a charter school that was guided by five character values: Leadership, Courage, Curiosity, Concern, and Integrity. We told the kids that integrity is doing what we believe is right, even when it isn't an easy or comfortable choice. I think our definitions are aligned. Of course, if we learn a better way or our thinking is changed, then what we know to be right can change -- actions of integrity.
Unfortunately, we have created and support an economy that is so heavily flawed, it doesn't serve us.
I wish it didn't take me a year in business school to earn a master's in finance to realize all this myself first-hand. Maybe I was just being naive or thought I could make a difference. Ultimately, I didn't have the drive or discipline to take on the status quo. Instead, I am making small changes for myself and have returned to the classroom so that I can try and make a difference for the next generation!
