Hard work without goals is like players with no score to make. Have goals. And have goals not just for success, have goals to be the person what is needed to achieve those goals. Goals are just inspirations to be that guy/girl.
Have goals to wake up with the excitement for the day, and not with catching up on pending things to do. Hard work is no measure of success. Run, but in the right direction. Have time for strolling, but stroll when you want to stroll and have set aside a time to do that.
