But my question to you is, which among them have the biggest impact on you and why?

A few months back, I was able to read "Truman", by David McCullough. Now, biographies can be laborious, but this one captures the detailed essence of one of the men to make multiple landmark decisions that changed the face of the planet forever. The entire 996 pages is worth reading.

What's striking about Harry Truman is how he embraced a very simple lifestyle, despite everything else, even while in the White House. All through his life, he never lost his sense of values of family, true friendship, focus and physical fitness. In fact, today, we might call him a fitness freak, (except for the shot of bourbon following each mornings exercise session).

He frequently retreated, much to the chagrin of the Secret Service to hideaways, really cherishing his time in Key West. He loved his time off.

And then in the office, he hits it hard. He usually accomplished more than what people around him thought possible. He worked incredible stints. And he usually pissed a few people off with his habits, especially those who couldn't get out of their own way.

He was doggedly persistent, blowing away entire teams of staff with his energy, purpose and convictions. "Give 'em hell Harry!" was way more than a slogan.

One part of the book that is really worth reading on its own is the chapter on the 1948 presidential campaign. It shows how driven Truman was. Despite incredible odds, and adversity, brutal media swipes at him, he managed to pull off one of the biggest upsets in history. Dewey, on the other hand, slowly destroyed himself, week after week.

So what's my point? There are several takeaways here. First of all, he knew what he wanted. He never stopped till he got it. NEVER! He stayed incredibly fit, well into later life. He knows when to retreat, and would frequently mentally withdraw to rejuvenate his mind and spirit. Incredibly organized, scheduled, and focused.

Sound familiar? It should, as these are the same characteristics of the most successful and happiest men and women throughout history.

And of course this is the very same philosophy Perfect Practice continually asks its members to learn and adopt.

What exactly are the steps? Here's how Harry Truman would do it using our platform:

1. Find out FIRST exactly what you want. And this of course changes throughout life. Regularly seek the guidance of your coach, and your soul.

2. Strong and stable data management and retrieval system. Use all the most modern and fastest tools available to the biggest advantage, to save tons of personal time.

3. Staffing. No BS here. Only hire appropriate staff members. Lovingly guide those around you with vision and purpose, eliminate those who can't or won't.

4. Let everybody know just what you are about, and why. Kindly explaining to them the benefits of doing things your way. Don't pay attention to those who reject your philosophy.

5. Austerity. Accumulating eventual wealth, even having miserably failed or bankrupt (like Harry).

6. Continually reassess, adjust and fine tune. On a regularly scheduled basis.
