Small habits are easy to implement and yield big rewards. Pick one of these habits to start this winter. I would love to hear your results!
Prepare for tough moments. Think through controversial meetings in advance: who might challenge you? What might they say? What will you say in response? You actually can predict what tough things will come up if you sit down and think about it. Systematically planning for difficult interactions or tricky situations will make you brilliant when they do come up, rather than thinking of the perfect remark six hours later.
Make quicker decisions. Many people get paralyzed thinking they need more data. Practice making a quick decision. Quick decision-making is a key executive skill, and research shows that it is more effective to make quick decisions and course correct as you go than to collect more and more data and put off decision-making.
Work on strategic projects first. Obviously this will get you to do more strategic things more often. Accomplishing high value things also boosts dopamine, a neurotransmitter in your brain - the same one you are flooded with when you are in the early stage of love. Talk about putting you in a good mood!
