According to http://www.wordbypicture.com/definition/stagnate/ the definition of stagnate is: To cease motion, activity, or progress; to come to rest; to cease to advance or change; to become idle or cease to flow. I think that describes it perfectly. Sadly, that's not a delightful picture. You are never going to find yourself sitting still. Get moving!
Start volunteering for things. Help out when you hear help is needed. Help people, help animals, help our environment. Try this, try that, try the other thing. But whatever you do, just start trying. Eventually you will discover something that really gets your juices flowing. When you immerse yourself into something the feelings that come over you are your spiritual barometer. A barometer is something that determines altitude, well your spiritual barometer can help determine your attitude.
What is your attitude when you are assisting the elderly? What is your disposition when you volunteer at the local animal shelter? What state of mind do you find yourself to be in when you rally your co-workers to "go green" at work? Pay attention to your spiritual barometer. It will clearly measure if you are in the sort of service that will Awaken Your Spirit. The feelings you get when you are involved in the service of others is one of the best ways of helping you find yourself. So don't just sit there, get lost!
