There are two types of people that you can surround yourself with, those who lift you higher and those who drag you down. If you spend your time with those who are trying to drag you down to their level then you should not be surprised when you do not fulfill your true potential in life. Having those who lift you up around you will inspire and motivate you, and this also has mental and physical health benefits as well. A positive frame of mind leads to better mental and physical health, and your days are filled with positive thoughts instead of negative emotions. A strong support system is critical, and keeping positive people around you who brighten your day and improve your mood make you far more likely to be successful and well adjusted.
The decisions that you make in life will impact your happiness and your future, so it is important to make the right choices in life. Examine each relationship[ that you have and then decide whether this person enriches your life or just adds negativity instead. Happiness is contagious, and so are negative emotions. Some people are optimistic and others are pessimistic. Make a choice to surround yourself with people who view the glass as half full rather than those who see it as half empty. Either way there is a half a glass of liquid, but those who see it as being half full will also see the rest of the world in a more positive and upbeat way as well.
