A great attitude maximizes your strengths and offsets your weaknesses.
Never underestimate the power of a positive mental attitude. How you feel will be reflected in the people around you. If you exhibit high energy, it will charge up others.
Also, when you look like you’re feeling great, people will have more confidence in your ability and choices. This may lead to you gaining support and resources. That, in turn, can help drive further success. So smile!
On the other hand, a bad attitude will negatively impact you. No one wants to work with a Grumpy Gus.
It’s up to you.
