The air is transparent,
only when you suffocate do you realise how much you need it.
The water is transparent,
only when you are drowning do you realise how powerful it is.
The diamond is transparent,
only when the pressure is strong and fire is hot will it be formed.

The spirit is transparent,
only when you lose it do you know that you once have it.
The emotion is transparent,
If you don't show it nobody will know it.
The will is transparent,
only when you exert it do other people feel it.

The voice is transparent,
only when you say it then you can hear it.
The warmth is transparent,
only when you feel lonely do you so so much crave it.
The end is transparent,
only when you reached it do you realise how dark it is.

"When you hate to do what you do, it becomes a job."
