[Cadaverous Pallor]

Don't underestimate what consistent loss of sleep does to your judgment and temperament. Same goes for consistent skipping of meals and showers. You can't be of use to anyone (including yourself) if your basic needs haven't been met.

If you can't manage your conditions, manage your expectations.

Many of us have a voice inside our heads yelling at us all day long, telling us what we should and shouldn't do. You may think this voice comes from others, from pressures outside of yourself. You are wrong. It is a manifestation of perceived pressures, of a constructed reality, and it has nothing to do with anyone else. You have no need to follow its dictates. Once you recognize this you'll be able to fight it.

When you're not sure how formal you should dress, always err on the nicer side. Being the best dressed person there is better than the alternative.
