Patience; accomplish thy labor; accomplish thy work of affection!
Sorrow and silence are strong, and patient endurance is godlike.
Therefore accomplish thy labor of love, till the heart is made godlike,
Purified, strengthened, perfected, and rendered more worthy of heaven.

The real test is not whether you avoid this failure, because you won't. it's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.
Know it for certain that without steady devotion for the Guru and unflinching patience and perseverance, nothing is to be achieved. You must have strict morality.
Soon I knew the craft of experimental physics was beyond me - it was the sublime quality of patience - patience in accumulating data, patience with recalcitrant equipment - which I sadly lacked.
