In life, he encountered many problems; he always thought they were moral issues in the past. Now, whenever life is difficult, he feels it's due to his lack of effort.
Every time he feels he's not trying hard enough, he tries even harder.
So every time he has a conflict with someone, he resorts to more effort as the solution. Thus, he endures, yields, and practices Tolerance.
As a result, he always finds himself in a position of sacrifice.
Life is immensely difficult.
He has no solution for this, except to try harder.
He builds this grand house for the primitives, feeling utterly anxious.
Afraid they will be dissatisfied with it.
Constantly feeling that his manual skills are inadequate, his handiwork too crude, his strength too small, and his endurance too limited.
This is the dilemma he currently faces.
So he can only train more.
Work more, endure more fatigue. No shirking, no complaining.
