That is fine for the first flight, but the connections can quickly turn into a mess. Also, after getting there an hour early, you grab a beer, sit around, and then the flight gets delayed or cancelled. I've noticed it is stressful until the plane for my final connection going back home leaves the ground.
If you don't have to get somewhere at specific times and events, no problem, just chill and you'll get there eventually. If going to a planned meeting, or giving a talk, etc., it can be very tiring.
