There are five major brain-wave types, each correlating to a different state of consciousness. “Delta,” the slowest brain wave (meaning the one with the longest pauses between bursts of electricity), is found between 1 Hz and 3.9 Hz. When someone is in a deep, dreamless sleep, they’re in delta. Next up, between 4 Hz and 7.9 Hz, is “theta,” which correlates to REM sleep, meditation, insight, and (as is often necessary for insight) the processing of novel incoming stimuli. Between 8 Hz and 13.9 Hz hovers “alpha,” the brain’s basic resting state. People in alpha are relaxed, calm, and lucid, but not really thinking. Beta sits between 14 Hz and 30 Hz, and signifies learning and concentration at the low end, fear and stress at the high. Above 30 Hz there’s a fast-moving wave known as “gamma,” which only shows up during “binding,” when different parts of the brain are combining disparate thoughts into a single idea.

Reageer niet meer op mails
Stel in je mailbox een afwezigheidsassistent in. Doe dat twee dagen voor je vertrek zodat er geen taken meer bijkomen, adviseert Deusings. Reageer niet meer op mails, anders gaan mensen ervan uit dat je dat gedurende je vakantie blijft doen. En dan heeft je out-of-office-reply geen waarde meer. Hetzelfde geldt voor de terugkeer; laat je automatische bericht één of twee dagen langer doorlopen, zo geef je jezelf de tijd om je mailbox op te schonen en rustig op te starten.

Whilst you should pursue excellence in technique and strive to continuously improve an athletes skills, it is ridiculous to try to coach every athlete you coach to achieve the myth of technical perfection.
“Textbook” perfect is just that – perfect for still images in textbooks.
