Some people say that the ego is bad, however, I think that the ego is good. The ego might be one of the most useful things that we have.
The first way to augment your ego is through weight lifting. The heavier weights you can lift, the more you will augment your ego and self-esteem.
Second way is to lower your body fat percentage. Super easy to do this; 100% carnivore diet, only meat. No vegetables, no fruit, no starches, no beverages besides black coffee and water.
Third, perhaps it is physiological thing. Sleep 8 to 12 hours a night.
Fourth, challenge the ethics and morality you were raised with.
