Hesitation will be confronted when being asked the purpose of living during a chat with your friend. 

The classification can be carried out with three categories approximately as followed,

Dependence on reality or in other words, too opimistic ingredients spawns the 'idealism'.

I would rather call ' idealism' thanks to their naiveness of imagination and expectation to mystery.

Acutually, they are the kind that would hardly stop in a cafe on the corner of street, order a cup of expresso, and think about what they are fighting for.

After all, they are simple, lovely while not adaptable to the present society.

Here comes the second group. Ambitions are their cellphones that would accompany themselves everyday. They have plans, future anticipation, passion, most of all, realization makes them wiser appareally.

Yet, the strongest disappointed and groomy adjective words can be the most suitable descriptions for them.

Their motivation is so scarce that half of daytime is their dream time without proper action.

Conclusively, internal elements overwhelm the external factors.

Admirations attend to the last part. Characteristics like aggressive, sensible, rational, ambitious, etc. are their sons and daughters.

Meanwile, the proverb '2 sides of 1 coin...' undoubtedly predicts the similar circumstances.

They receive esteem while they bulk their lifetime as sacrifice and fundement of success.

The thoughts,' No happiness before success', 'what if I make none efforts if a better condition meets my need', ' I would get returned in the near future for the substitution of the frustrations right now',..., are their doctrines and disciplines that clinging to.

Finally, a question will naturally be raised,'what might the purpose of living?'

No answers are required only if your considerations are being stimulated.
