If you don't succeed at the first attempt

Have you seen how a kid walks for the first time? It starts with a very unstable, and very shaky step. Probably, the kid may not move more than 1-2 steps and end up falling. So shall the kid stop walking or even stop trying to walk? Just look at the kid after a month or two; the kid runs to and fro relentlessly. This process is Universal. The first attempt, almost every time, is a failure - a major or a minor one. And that is a major part of learning how to be a success.

The first time you work on an MS Excel sheet, the first time you make a presentation, the first time you give an interview, all of them have a good chance of not going well. Many times they are not useful too. With proper supervision and maybe triple the efforts, you possibly bring in a positive outcome. But that does not indicate your capabilities.

As you work again, you start understanding the nuances of the tasks, improve your knowledge, and learn how to accurately complete the work. Depending on the complexity of work and your talent, the time taken and the opportunities required to completely learn the task are defined.
