If you open a restaurant expect at some point a good dose of anxiety, that feeling of dread and impending doom. It could be a sign that you are doing something unusual and new or it could be a sign that you are doing something very wrong and fiscally dangerous. Or all of the above.
Anxiety is a warning from the brain to proceed slowly and thoughtfully. In regard to opening a resaurant or base jumping off a cliff anxiety attacks only happen during that intense phase just before you open or jump. Once you the door is open or your body is in the air and there is no hope of turning back, trust me, you will be too busy to have an anxiety attack.
Don't be alarmed if you find yourself doing strange things like sleeping in a warm bathtub rather than your bed or drinking tequila for breakfast. But let's save that for the conversaation we'll have on the high probability of self medication among restaurateurs.
Hint; When you see a therapist and she offers to give you counseling or sleeping pills take the pills.
