What keeps you busy and interested in a day-to-day life.. ??
Some food for my brain.?? There is a downside for this. The amount of fun you get out of this is directly proportional to the amount of effort you put in.. :). And the steepness increases as you progress which, in some sense, related to the law of diminishing marginal utility. The term lazy is invented exactly for this situation When the marginal utility is almost zero, you tend skip things.. :( And you need to really invest considerable amount of time and effort to improve the situation.
Some positive emotion like love and like..?? I hate positiveness ;). Because they are logically incorrect. If you agree that there is something positive you are also agreeing about negative emotions.. which is logically against our first premise.. :(
I hate negative emotions.. (This is a logically correct sentence.. )!!
ps: All this said and done.. isn't the whole discussion boring??
