So if stress is good — if it is the reason we take action on anything at all — then how do we know when we have stress overload? Experts say there are 4 categories where too much stress can have bad results: cognitive, behavioral, physical and emotional. Three cognitive signs are inability to concentrate, constant worrying and seeing negativity everywhere. Behavioral stress can manifest in things like procrastinating too much, eating too much or alcohol abuse. Too much stress can affect us emotionally by causing moodiness or agitation and a feeling of being overwhelmed. Physical results of too much stress include aches and pains, more colds and a lowered immune system. You can see how these things can hurt not only your life, but also your business. My next tip will cover some ways to combat stress.
