Today marks the start of the second half of 2021. I didn’t realize that 2021 is halfway over until a friend brought it to my attention today. It caught me off guard and got my wheels turning a bit. I reflected on how different from the beginning of the year—and a year ago—things are today.

I figured things would be different this year, but I didn’t anticipate this pace of change. If someone had told me in January that airlines would be canceling summer flights because they can’t find enough staff to meet the demand, I’m not sure I would have believed it. This is the same industry that, with empty flights, significantly cut capacity and received government assistance last year. But here we are today, and that’s exactly what’s happening.

My big takeaway today is that a lot can happen in a short time, and 2021 is a testament to that. I’m looking forward to what’s in store the second half of the year!
