Satisfaction of teaching

By: Vollie Brink

When I was young my boss would ask me “why are you not working?”, And now I am asked “why are you still working?”

I never gave anybody an answer as to why I am still working and today I thought about it and what I should answer. I don’t want to be pretentious and also not to act ‘holier than thou’, but my short answer is that every time I get it right to solve a problem (engineering problem) it gives me a ‘great kick’, an adrenaline rush, and satisfaction.

‘Theory helps us to bear our ignorance of facts’

I was doing some spring cleaning in my home office and I came across my old study guides when I studied development administration at the time when I was working for the Development Bank.

I also read that Higgott (1983: xii) said: “There is no theory of development in the formal sense of hypothesis which have been verified in a systematic manner through empirical study”, and then further a warning by George Santayana: “Theory helps us to bear our ignorance of facts”.

Keep your pencil sharp

I have been writing a letter to a family member about the importance of putting important ‘things’ in writing and I thought perhaps I should share my experience with you. I know that there are many people who do not appreciate it to put important issues, decisions and matters on paper, (now a days on your laptop, smartphone, tablet, or computer), but it is an extremely important and essential activity that prevents problems, disputes, issues, and even expensive litigation and fruitless time in court. The times when I have not put things on paper was the times when I was in trouble, which is Murphy’s Law and it was lessons learnt and never forgotten.

It’s a matter of time management

I want to discuss a sensitive matter with you and I would really appreciate your feedback on how you feel about this issue. I have previously discussed this matter but I feel we must talk about it again – the matter of selection of piping material at design stage and for construction.

In the engineering business the majority of the lower tier staff falls in the category of not being registered and their competencies acknowledged and we need this people and we need to up-skill them and record their competencies and control them to be responsible for what they are doing.
