If we want to grow in mindfulness we must accept what mindfulness finds. It may be boredom, irritation, or fear. It may be weakness, inadequacy, or faults. Whatever it is, that is the way we are. That is what is real.
Mindfulness simply accepts whatever is there.
If you want to grow in mindfulness, patient acceptance is the only route. The process cannot be forced and it cannot be rushed. It proceeds at its own pace. Mindfulness directs the power of concentration. Mindfulness is the manager of the operation.
