In life, many things happen beyond your control. Sometimes, you do your best but the results don't show that. This is a reality of life that you need to understand and realize that when things don't go the way you expect, you are to figure out why instead of just sulking.
On the journey of life, you have to learn to be intentional about your actions.
Now, there are generally two groups of reasons why things may not go your way. One is the stuff you did or didn’t do -- basically things under your control. While the other consists of things you could never control; like forces of nature, luck, and so on.
Although there isn’t so much you can do about those things outside your control, it is still very important that you seek to identify them and label them appropriately.
The goal here is to give yourself the best shot at getting it right the next time. Identifying the reasons under your control and working on being better at them gives you a better chance on your next try.
When you fail, learn from it.
