There is a Rule of Thumb

There is a Rule of Thumb
That what will come will come
We'll get to where we've got to get
And come from where we're from

No need for feeling pride
No need for feeling glum
Let's side by side enjoy the ride
For what will come will come

There is a guarantee
That what will be will be
We'll miss the things that we will miss
And see what we will see

The doing has been done
The ending has begun
Let's side by side enjoy the ride
For what will come will come
