Scientists grew trees in a sealed biosphere and couldn't work out why they fell over before they matured. They eventually figured out whilst they provided the perfect growing environment, it was lacking wind which provides the stress to ensure the trees grew strong enough to support themselves.
“Sometimes when you're in a dark place you think you've been buried, but you've actually been planted.”
Getting over a painful experience is much like crossing the monkey bars. You have to let go at some point to move forward
We may have to struggle to achieve our goals, but our struggles may yield as much growth as our learning. The strengths we develop in overcoming challenges will be with us in the eternities to come. We should not envy those whose financial or intellectual resources make it easy. The stuff of growth was never made of ease, and persons who have it easy will need to experience their growth with other sacrifices or forego the advancement that is the purpose of life. Dallin H Oaks Learning and Latter-day Saints Ensign, April 2009
If we approach adversities wisely, our hardest times can be times of greatest growth, which in turn can lead toward times of greatest happiness… ...Learning to endure times of disappointment, suffering, and sorrow is part of our on-the-job training. These experiences, while often difficult to bear at the time, are precisely the kinds of experiences that stretch our understanding, build our character, and increase our compassion for others.
