1. Increase knowledge
We can read to improve knowledge. Or ask and share stories with more experienced people. Learning not only the success stories but also the failures.
2. Increase experience
Practical always beats theory. By practising the job often, the probability of making mistakes decreases.
Most of the time, coffee are spilled because we are reading the news on our computer and we forgot about the coffee. Or when we drive while talking on the phone, the chance of meeting an accident increases. Mistakes usually finds people who multi-tasks. It is important to give our 100% focus to what we are doing.
Allocate more time to a task. More time to prepare, more time to work on the task slowly, more time to check, less chance of mistakes. Reach earlier if you have to. Stay later if you have to.
5. Check and check
We should always check our tasks after completion. How many times did you spot a mistake after you decide to check one more time. Never allow laziness get the better of us.
Finally, always have contingency plans.
