Why is it some people fail miserably and others thrive?
Partly to blame is the consistency of your trust in Him. Trusting in Christ when turmoil arises, but then forgetting about Him when smooth sailing abounds, does not show consistency, nor commitment towards Him. Do difficult times shock you into awareness of needing Him where calm times lull you into a sense of false security, thereby causing you to feel you can solely depend upon yourself?
Christ cares as much about our tiny trust as our big trust.
Its all trust to Him. All trust is just Faith. People around you may not notice but the ever-present Christ who is with you sees all. Consistent trust is vital to flourishing in His presence.
