I 've made it a point to have an impact through institutions.

 A construction bricklayer can point to a building he worked to build by pointing to the very bricks he laid.  "See I did that!"

So, I, too, have tried to use my worldly and professional training to leave behind my pieces of work that are incorporated through some enterprise or governmental project into some lasting edifice for the societal good.

For instance, as a college professor, I was molding the minds of my students to think wisely in coming to their opinions and beliefs.  While teaching at a community college in the Chicago area, I worked to improve the community colleges of the nation by participating with a professor from the University of Chicago, in a statewide study of the state's Illinois Community Colleges Board at its tenth year anniversary.  I understand the study has proven successful in laying down the permanent features of the community college system of education.

Also, I did what I could to promote peace by encouraging the US military to expand its bases to nearly all countries in the world that by their mere presence, the US could demonstrate its dedication to a peaceful resolve of international problems.  A project that netted some 190 countries granting permission for US installations on their soil.

And, it's been fun for me to see the bricks being laid firmly into the material for mankind's future.

Not the less of an impact, I encouraged the FBI-institution to become international by talking it up with agents I knew.
