Hi, here are my suggestions:
The [most] important step to [acquiring a] good reputation is business etiquette. The first rule of business etiquette is [to be on time]. {or maybe more generally “not wasting other people’s time”} The credibility [of] a person who is always late gradually decreases. The second rule is politeness and respect. The third rule is [an] attitude [of hard work]. If you are able to work [diligently], you will quickly move up the career ladder.
Thank you very much, Luschen!
