"If I've achieved anything"

[dupond]

Hi everyone

How would I translate a sentence such as "If I've achieved anything, it's providing an example of what not to do"?

Would this sentence convey the intended meaning?

Si lograra algo, sería demostrar lo que no debes hacer.


Or would the Spanish translation just avoid using "si" and say something such as "No he logrado nada pero he demostrado lo que no debes hacer"?

Thanks
