Be early

Allow enough time so you can be early. Being late shows that you are selfish and you are not in control. Growing up my father impressed the importance of being on time. For every minute I was late coming home I was grounded one day. If I was 30 minutes late, then I was grounded a month, a hour and a half ... well then I was grounded for the summer. Growing up I thought that my dad's punishment for being late was harsh, but as an adult I totally get why he was so strict regarding being on time. At my previous company, my manager used to say if your are on time, then you are late. Make sure you are early and not late so you can be counted on. After all it's the right thing to do and models the way for others
