This is an extension of the earlier point. When you learn, you can show

Iam a hands on leader. I love to lead from the front, however Ialso would like my
staff to grow. One th ing every leader must realize is that true professiona l growth
does not take place because you have grown in your position. It only takes place
when you can assist other's in achieving their professional goals. Since a
company is a sum of its parts with human resources being the most important
resou rce, a considera ble investment to develop this resource would pave the way
for a healthy organ isation. This has also its effects on their families and the
environment. I believe that the reading of various concepts, spiritua l and material
has given me an abi lity to integrate into a process for sustaina ble growth .
