[单选题]5 Ways to Focus Your Energy During a Work Crunch Work invariably ebbs and flows,cycling between steady states,where we feel more in control of the pace and workload,and peak periods,where the difficult work situation hits us hard.Unexpected setbacks or even vacations and holidays can create disorder and tension.Maintaining focus and managing energy levels become critical as tasks pile onto an already full load.When you're in your next work crunch,there are a few things you can do to focus and manage your energy more productively:41.When an acute period hits,it's easy to resist the fact that it's happening.We wish for things to be like they were last month,or we long for the pace we had during vacation.By not being present to the here and now,we drain our energy by pondering on the situation.In fact,physicists define resistance as"the degree to which a substance or device opposes the passage of an electrical current,causing energy loss."In the case of a diffcult work situation,the more you oppose what's happening,the more energy you lose.Acceptance does not mean giving in.On the contrary,it means acknowledging the reality of the situation with awareness so that you can take clear action.42.Acceptance is particularly difficult given the underlying emotions that an acute work crunch can bring.Negative thoughts often predominate.David Rock,director of the NeuroLeadership Institute,suggests that,rather than suppressing or denying an emotion,an effective cognitive technique is labeling,whereby you take a situation and put a label on your emotions.By assigning a word to what's happening,such as"pressure","guilt",or"worry",Rock's research shows.you can reduce the arousal of the limbic brain's fight-or-flight system and instead activate the prefrontal cortex,which is responsible for our executive funcLioning sk川s.43.A research out of the Universiry of Pittsburgh shows that anxiety directly impacts our cognitive functioning,especially those areas responsible for making souncl decisions.Don't fall into a victim mentality.believing there are no choices or that you don't have control.Instead,bring greater vigilance to assessing your priorities,making tough trade-offs,and incorporating self-care where you can.44.Other people can be a real energy drain-or gain-during work crunches and set-backs.Pause and consider how you can renegotiate deadlines,set tighter bounciaries,or ask for more support during this time.Many of us pride ourselves on not bothering others and being self-reliant.The.se are great qualities,but there are times when we need to ask for help.Ask your loved ones for more help on the home front.Share the weight of the accountability for projects with your colleagues by delegating or teaming up,versus doing it all on your own.45.Probably the toughest thing of all during a work crunch or setback is how easy it is to beat yourself up,especially when you aren't hitting your high standards for work,Annie McKee,author of the forthcoming book Howio Be Happy at,Work,says this:"If you really want to deal with stress,you've got to stop trying to be a hero and start caring for and about yourself."43选？

E.Control your negative emotions
