“幸福在路上”用英语怎么说？

Happiness is on its way.

有一首歌就叫 love is on its way
歌词：
So hold on another day
Cause love is on its way
You’ll find it’s gonna be ok
Cause love is on its way
Its alright you’ll find a brighter day
Cause love is on its way

在路上经常是用 on somebody's way 来表达
比方，A和B打电话，
A: Where are you? The party has started. 你在哪里？晚会都开始了
B. I am on my way. I will be there soon. 我在路上. 很快就到。

Happyness is just a step away.
幸福仅一步之遥。（字面意思）
有的时候，语言是很微妙的，同样的话，用另一种方式来表述的话，就会有一种韵律和美感在里面。也许这只是我的浅见？

happiness on the way本回答被提问者采纳

Though happiness is far away,it is still on the way.我采用了增词法，显得流畅一些。

楼上的那属于中国式英语，应该是：happiness is coming.
