Capo 2

Intro: Am F C G7
       Am F C E X2

Am        F                 C                C
Feeling my way through the darkness
Am        F                 C                C
Guided by a beating heart
Am       F                  C               C
I can't tell where the journey will end
Am      F                  C             C
But I know where to start

Am       F                  C               C
They tell me I'm too young to understand
Am      F                  C                 C
They say I'm caught up in a dream
Am       F                   C                 C
Well life will pass me by if I don't open up my eyes
Am      F                    C                 C
Well that's fine by me

Am      F                C          G7
So wake me up when it's all over
Am      F                C          E
When I'm wiser and I'm older
Am      F                C          G7
All this time I was finding myself
Am      F                C          E
And I didn't know I was lost
X2

I tried carrying the weight of the world
But I only have two hands
Hope I get the chance to travel the world
But I don't have any plans

Wish that I could stay forever this young
Not afraid to close my eyes
Life's a game made for everyone
And love is the prize

[2x]
So wake me up when it's all over
When I'm wiser and I'm older
All this time I was finding myself
And I didn't know I was lost

Didn't know I was lost
I didn't know I was lost
I didn't know I was lost
I didn't know (didn't know, didn't know)
