What words you use in your everyday life matters a lot. Think about not using negative words but positive, winning words. Words that lift you up and elevate those around you. Even when things get tough. If your team or your family are facing challenges. Do not mention them as a failure, but as a possibility and an opportunity to learn and to do or experience something even better.
What words do you use most frequently? Start making a list out of the words that you use most frequently. Are they the words you would like to use? Are they the words that will help you to be your best self and to lift others? Then make a new list the words you would like to use. Choose the most positive and powerful words you can think of. And start changing your vocabulary. Step by step. Start talking like a positive person, always. Being aware of your language is the first step.
The language you use and the words you choose determine the way you feel and how you see things. So start by looking at the glass as half full, and not half empty!
Wish you the best. Take care. Namaste.
