I need to figure this out

The swiftest way to let you know
The fastest route to let you grow
The quickest cut to let you go

The time it takes to let you know
The smile I’ll fake to let you grow
The words I’ll make to let you go

The result it makes to let you know
The end of me to let you grow
The outcome of this to let you go

I need to figure this out
