Idiom in English

[ruzu27]

Hello,

In German there is an idiom which says (approx. translation):

'why do things the easy way if you can also make it complicated?'

Is there an equivalent in English? Thanks for your help.

I have been searching but I haven't found but the opposite: idioms like
the KISS principle: Keep It -
- Simple, Stupid
- Simple, Silly (for children)
- Short and Simple
- Sweet and Simple

Keep the Simple Things Simple and the Complicated Things Possible

"Everything should be made as simple as possible, but no simpler." - A. Einstein

But not the other way round.
I'm curious about it, so I'll be waiting for the NES to answer.
