Ethics & Integrity

How does one convince others that ethics and integrity are part of your core values?  I believe I cannot be effective in my job if people do not trust and believe in me - my word is therefore my bond.  I never lie - mainly because it is unjust to others, but also because I cannot remember everything that I say and it is therefore much easier to rely on the truth.  I use the Golden Rule as a guiding principle and always try to think of the impact of my decisions on people.  These are of course personal claims that should be confirmed by contacting my references.
