“Stay away from negative people. They have a problem for every solution.”
— Albert Einstein
People you spend the most time with add up to who you become. If you spend time with those who refuse to take responsibility for their life, always find excuses and blame others for the situation they are in, your average will go down, and with it your opportunity to succeed.
However, if you spend time with people who are trying to increase their standard of living, and grow personally and professionally, your average will go up, and you will become more successful.
Take a look at around you, and see if you need to make any changes.
