It's not what happens to you, it's what you do about it.

A lot of time when a certain thing happens in our life we tend to blame others, or we tend to justify it or we give excuses so that we feel better. Doing so doesn't give any solution or solve the incident. Instead, we should always look for what we should do about the incident to solve the issue and prevent it happen again in future. For example, I experience this in my workplace when production issue happens we figure it out what is the root cause of the issue and what are the solutions available to fix it and at the same time prevent it happen again in future.
The quote can be applied to any area of your life. It can be your professional life & personal life.
