Training

Never stop training. Exposing yourself to new ideas and thinking will enliven you and create energy which will rub off onto other people.

Never assume you know it all and that your thirst for knowledge has become satisfied.

Expose yourself to formal teaching and obtain different perspectives on life and dilemmas (see problems).

By keeping up to date with the latest trends and thoughts you will be able to survive in the modern world. Honing your skill base will mean you can keep that sharp competitive edge.

Not willing to train is arrogance. It is an assumption that you know everything and that you are always at the top of your game, which, of course, nobody ever is. Or will be.
