It is essential to get out of your comfort zone. Successful people are not limited to making easy decisions or living on their achievements and in a cosy little comfort. They go beyond all these things and set goals. This allows them to learn something new every day, to advance their life goals, professional and emotional.
“Life is not measured by the number of breaths we take, but by the moments that take our breath away.” ~Unknown
Work hard for what you want. Despite, or perhaps because of, obstacles that may arise, a strong individual is focused on her/his goals and will work tirelessly until she/he reaches them. They are willing to make sacrifices to ensure their dreams become a reality.
Remember that the success of others does not detract from yours. So rather than envy them, celebrate their good moves.
