咩叫興趣？咩叫慾望？咩叫鐘意?

they are 3 'steps'

first u need to hv interest in sth, perhaps u want to/are interested in learning an instrument. tht means u want to know more abt sth. this is interest.

then u hv the want/desire to buy an instrument and start learning (applying for music lessons and buying a piano, etc), tht's a further 'development' of the mere interest. u are not only 'interested', but also starting to do sth to achieve ur goal.

and, when u are learning tht instrument, u find it a gr8 fun and u love it more each day. u 'like' playing tht instrument. then u will take the initiative to practise it every day etc.

liking/loving a person is the same. first u hv to be interested in sb, meaning u would like to meet him/her, or make frds wif him/her (i.e. u won't hv a natural feeling tht u wanna stay aways fm him/her or even ignore him/her). then u might hv the desire to be frds wif him/her, tht u will start chatting wif tht person etc. finally when u find more and more similarities etc between u 2, then u grow more and more fond of him/her.

as for the reason part, it is basicly ur own feelings. u feel comfortable/gd/at ease wif sb, then u may be interested in him/her /want to be frds wif him/her /like him/her more day by day. therefore it's totally ur own sense towards it, there need not to be a reason (not compulsory)

興趣不同於鍾意。
興趣是與生俱來的興趣
例如馬嬲愛搶人類的袋，這個是他們的習慣、興趣
要他們不去搶，比登天更難。

而鍾意是培養出來，但千萬莫說一見鍾情。
因為一見鍾意又一講法。

興趣，有感而發，才會去發揮所長。
鍾意一個人，若果有原因的話
就不算是喜歡。
惑覺，很奇妙，想說亦說不清啊～
