Learning is of two types. One, learning in the form of the deep down understanding of a given project. Two, learning to be taken forward to ensure that the similar mistakes or rather shortcomings do not repeat while we do another project. Be it mistakes or shortcomings might have resulted out of various steps that we would have followed while trying to accomplish the task at hand in the given time. The amount of mistakes depends upon the newness of the task or the newness of us towards the task. The amount of learning from a task depends upon the mistakes we would have done, the hurdles we would have crossed and most importantly the thoughtfulness of us to find out the learning hidden either in a debacle or in an error near-missed.
The learning is directly proportional to the mistakes done. The mistakes are directly proportional to the tasks or things done or attempted. Hence, by following the mathematical rule learnt in school, the amount of learning is of course proportional to the tasks done. Do not get worried to know that your list of learning is too long, that your list of mistakes were too many! Be courageous and bold enough to believe the fact that you have done so much, attempted so much, accomplished so much in the given time. Take forward the learning and give your best to implement it at the next best needy occasion. That's how life moves on, that's how work goes on. So as work life.
Always try to perform your best. Do your duty to your best potential. Do not be too much conscious of not making any mistakes. Let a few happen, don't bother as long as you are taking necessary decisions respecting the time line that you have to follow. Learn from them and move on.
