Why our mind always live in habits? Why we are always making new habits? What will happen if habits are not formed? QN 1: What is connection between thoughts and habits?

QN 2: We (as a lay practitioner) are aware of our few habits like smoking but not all. 

Example: Morning tea habit (feeling to have tea). Similarly checking mobile time to time, watching TV, doing prayers and other religious habits. 

I was not aware of these habits from many years but now I'm aware of it. 

Main QN: Why is our mind always making new habits and gets trapped in habits?

OP: QN 1: What is connection between thoughts and habits?


The answer for this is given in MN 19:


  “Bhikkhus, whatever a bhikkhu frequently thinks and ponders upon,
  that will become the inclination of his mind. If he frequently
  thinks and ponders upon thoughts of renunciation, he has abandoned the
  thought of sensual desire to cultivate the thought of renunciation,
  and then his mind inclines to thoughts of renunciation. If he
  frequently thinks and ponders upon thoughts of non-ill will…upon
  thoughts of non-cruelty, he has abandoned the thought of cruelty to
  cultivate the thought of non-cruelty, and then his mind inclines to
  thoughts of non-cruelty.


The inclination of one's mind translates to habits in thoughts and actions.

  habits?


This is because we have the underlying tendencies or obsessions (anusaya) as found in AN 7.11 (or from here): 


  "Monks, there are these seven obsessions. Which seven?
  
  "(1) The obsession of sensual passion (or sensual desire).
  "(2) The obsession of resistance (repulsion).
  "(3) The obsession of views.
  "(4) The obsession of uncertainty (doubt).
  "(5) The obsession of conceit.
  "(6) The obsession of passion for becoming.
  "(7) The obsession of ignorance.
  
  "These are the seven obsessions."


Forming habits of sensual enjoyment e.g. sex , coffee, desserts etc. is due to the obsession of sensual passion.

Forming habits of self-improvement e.g. reading, fitness etc. is due to the obsession of passion for becoming.

According to this answer, the underlying tendencies or obsessions (anusaya) are a type of defilement (kilesa) or mental impurity that is caused by ignorance (avijja) in dependent origination (pratītyasamutpāda).
