So I suggest you look around and see who is at peace even when things are challenging and get to know them. Consider what is different about them from the folks who rock and real between the extremes of emotion or are devoid of emotion.
Who has the habit of kindness and a gentle spirit, even while they have a passion for their work and making a difference? Who balances realistic expectations with an optimistic outlook? These are good folks to get to know, to learn from.
Where do you find them? Find a place to volunteer your time and expertise and you will probably find such folks among long-time volunteers. Not all folks at church have achieved this way of living, but you usually find such folks there if you look for them. Is there someone in your family with a reputation for offering good counsel, always sharing a kind word and a willingness to lend a hand (but smart about not lending money)? Is there someone at work who stands out as having a capacity to bring perspective and balance to discussions?
When we pay attention, it is possible to find folks who live lives that can inform our own journey. They often welcome coachable (willing to learn) folks into their lives. If not, keep seeking, because somewhere God has a person, people, who can shine wisdom, hope and encouragement into your life.
We do not lose heart. Even though our outer nature is wasting away, our inner nature is being renewed day by day. 2 Corinthians 4:16
