In the case of a bird flying, it seems a natural act, and a foregone conclusion that it should succeed. In the examples you have given in answer to the previous question, was your success guaranteed, or was it important for you to try, regardless of a possibility of failure?

A bird flying is natural as well as taught to the young ones by their parents or their elder ones. So, one has to learn it through some of the properties which may breed in them naturally. Without any attempt and learning, nothing comes automatically. But it can be concluded that it should succeed. Our success was never guaranteed until to try again and again. In some cases, all results may not be favourable. But it is always essential to practise, try and put every efforts to get success.
