Early
Early. Arriving early is just what I do. To work, to the movies, to parties, and the airport. Arriving before everyone else gives me peace of mind, and it avoids having to rush.
In addition, if something goes wrong, you have time to fix it, and no one else even knows. So early helps other people as well. No one has to wait on you or for you.
Early isn't for everyone, and if you are a person who rushes or waits until the last minute, try arriving early. I bet you will enjoy it and have peace of mind.
