还记得阿公就很喜欢这样问我，“好吗？”，“开心吗？”。

每一次，我都会这样的回答：“好啊！”，“开心阿！”然后呢，阿公就会静静的别过脸去。脸上没有快乐，也没有悲伤，就是这样静静的。。。

几次过后，开始不明白了。阿公的意识是什么呢？我试着不一样的方式回答他，可，阿公还是一样的表情。。。就在那时候，脑子里开始不断地问自己，什么是好吗？什么是开心吗？

直到最近，因缘巧合下，看到了这样的一个讲解。原来，往往玩乐当中的快乐，其实不是快乐，而是一种错觉。。。美国心理学家做了一个这样的实验，他在老鼠的下丘脑背部埋入电极。只要老鼠按下杠杆，在微弱的电极刺激下，会让老鼠感到非常的快乐。于是老鼠会开始疯狂的压杠杆，直到十几个小时后的它感到疲惫为此。于是，研究者据此推断，老鼠的下丘脑中存在一个“快乐中枢”，而压杠杆这种“自我刺激”的行为可以获得快乐的情绪。如果用微弱的电极刺激人类的下丘脑的相关部位，即把这种自我刺激方法用在人的身上，会让人感到快乐，表现为微笑　或高兴的样子。由此可见，这种被称为“良好的感觉”，一样会人觉得是种快乐。。。

这忽然让我回想起阿公最爱问的问题。原来，往往我所谓的好，或是开心，其实是不是真正的发自我内心的好，或是开心？就连我自己都分不清，什么是什么。这当中的奥妙，会不会就连阿公他也是这样的疑惑呢？。。。

I can almost see it
That dream I’m dreaming but
There’s a voice inside my head sayin,
You’ll never reach it,
Every step I’m taking,
Every move I make feels
Lost with no direction
My faith is shaking but I
Got to keep trying
Got to keep my head held high

There’s always going to be another mountain
I’m always going to want to make it move
Always going to be an uphill battle,
Sometimes you going to have to lose,
Ain’t about how fast I get there,
Ain’t about what’s waiting on the other side
It’s the climb

The struggles I’m facing,
The chances I’m taking
Sometimes they knock me down but
No I’m not breaking
The pain I’m knowing
But these are the moments that
I’m going to remember most yeah
Just got to keep going
And I,
I got to be strong
Just keep pushing on,

There’s always going to be another mountain
I’m always going to want to make it move
Always going to be an uphill battle,
Sometimes you going to have to lose,
Ain’t about how fast I get there,
Ain’t about what’s waiting on the other side
It’s the climb

There’s always going to be another mountain
I’m always going to want to make it move
Always going to be an uphill battle,
Sometimes you going to have to lose,
Ain’t about how fast I get there,
Ain’t about what’s waiting on the other side
It’s the climb

Keep on moving
Keep climbing
Keep the faith baby
It’s all about
It’s all about
The climb
Keep the faith
Keep your faith
