Instead of feeling like your work is burdening you and pulling down your spirits, change your outlook on your company. Create for yourself the enthusiasm and passion to make a difference in your business;

Ask yourself:
1. What do people need that my organization could fulfill?
Great purpose based organizations put the customer first. Start with the customer in mind and find a deep seated, unmet need that you're passionate about fulfilling.

2. What turns my organization on?
What do the people in your organization seem genuinely fanatical about? Observe the behaviours and attitudes within your organization to discover where the real thrill is. For example; challenging issues like serving underserved populations, creating new paradigms, fighting for noble causes, or enlightening and empowering people.

3. What difference does my organization want to make?
Asking this question will help you discover the source of passion that brings you out of the dull moods surrounding your work. Find the thrill of doing business by figuring out exactly what problem you're driven to solve.
