Nothing can be achieved by a person who is prone to decadence

न व्यसनपरस्य कर्यावाप्तिः॥६९॥

na vyasanaparasya karyāvāptiḥ ||69||

" Nothing can be achieved by a person who is prone to decadence."
Chanakya simply states a very important fact in a simple aphorism.  Vyasana is the habit of wasting ones money, time or energy to one's own detriment.
Manu enumerates many habits of otherwise sensible persons and rulers as detrimental and harmful for the welfare of the Individual or the ruler. They are:-
1.  Tendency to go for hunting too frequently.
2. Costly and wasteful sports ( like dice play, horse racing, games of chance like gambling etc.) 
3. The tendency to sleep away the day time too.. it is termed as the destroyer of all achievements.
4.  Insulting others.
5. Adultery and contact with fallen persons to fulfill uncontrollable carnal desires.
 6. The arrogance and self delusion stemming out of excessive consumption of alcoholic beverages. 7.Spending too much time in dancing,
8. Singing
9 futile debates
10 wasteful loitering.
( It has to be clarified that dance, song or debate by persons in a health and aesthetic manner and at the appropriate time is not an unhealthy practice.. but spending away all their time in these pastimes, when such things are not their profession can pull down a person or a ruler to penury because the time earmarked for their own avocation are spent in these). 
These are the ten vyasanas that can come out of excessive personal desires and whims.
There are eight evil tendencies that arise to a man or a ruler through excessive impatience and anger. 
They are:-
1.Tendency to accuse someone falsely.
2. Out of graft and excessive lust, tendency to brush aside the favourable advises given by well wishers.
3. Keeping personal enmity even with innocent souls.
4. Intolerance and jealousy when one sees the welfare of someone nearby.
5.  Tendency to ascribe evil even in the good qualities of other .
 6.Stealing others' wealth and not returning the borrowed funds.
7 Using very bad and foul words which hurt all others.
8. Physical vilolence against others like beating or assaulting  when one is in utter rage.

The above eighteen qualities can make the king a pauper and an ordinary human being into a fallen man.  These bad qualities simply prevent a ruler or a person from acting in a sane and composed manner, makes him bereft of the tendency to plan his strategies properly and execute such plans effectively.  The qualities when present in a boss, percolates down the hierarchy and can  result in the destruction of organisation or even States.
True, one can see how staggering  the simple aphorism of Chanakya  is in its impact when evaluated in the right light.   These qualities are enumerated here to warn the people to shun  them and not to prompt them to acquire some habits if they have not acquired the same.
