Effervescence

If effervescence is only the key

There is no real keys

The deepest precipitations also keys

The core is all keys meant for different doors

Pick the right key at each moment and enjoy

Turn the knob and enter the room and simply stay

Effervescence is at times a really broken key

What are those in your hand at present

Happiness and melancholy all are keeys

Down the hill and up the hill are too

Roller coaster and slow ride also there

Use it wisely and live smarter at your pace
