In almost every case I've seen, when we feel anxious, confused, nervous, lost or that we have a lack of purpose, it's because we are looking inward. What can the world give 'ME', what can 'I' get out of this, when is it 'MY' turn.
And there is only one way to fix.
Focus your attention on serving others and giving.
Give service. Give time. Give advice. Give an experience.
An attitude of service is becoming more scarce by the day, yet doing this one single thing, will separate you from 90% of the so called 'competition'.
When you adopt this habit, good things cannot help but 'fall into place' for you.
Get out of your own head, and continually look for ways to be of service.
