These are my lessons learned from over 40 years in EMS and the Fire Service, and over 35 years of teaching EMS (also Nurses, and Physicians)
I think you'll find most relate to everyday life/jobs also.
RWT1405's Rules of EMS
1) Practice does NOT make perfect, PERFECT practice makes perfect.
1.A) Practice until you get it PERFECT!
1.B) Then practice until you can't get it WRONG!
2) Training is learning the rules.
2.A) Experience is learning the exceptions.
3) Experience is a very cruel teacher! (Trust me!)
4) Just because you CAN do something, does NOT mean that you SHOULD!
5) The most important things are simple.
6) The simple things are ALWAYS hard.
7) If there is little to be gained, there is little to be lost.
8) If there is a lot to be gained, there is a lot to be lost.
9) Air goes in and out, blood goes round and round, ANY deviation is a PROBLEM!
Last, but not least!
10) Not everyone is cut out for EMS (or Medicine).
10.A) HOWEVER, Wawa needs good people, to make good hoagies, at 3am.
