First Image Training by JosephineLui

Cause and effect can bring us either good or harm, and it is entirely our own doing.

For instance:
Preparation: A presentation can be great or just so-so, depending strictly on whether sufficient preparation is done before ex*****on.
Procrastination: Putting things off leads to extra costs, higher stress, or wasted effort in the long run—whether in our homes, health, or education.
Recklessness:
To avoid the devastating effects of a speed-related crash, a person must choose not to drive while intoxicated. An excited or drunk brain is simply incapable of making safe, split-second decisions.

This matches the old saying, "What comes around, goes around." The actions we choose today (the cause) are the exact consequences that will return to us tomorrow (the effect). While this phrase sounds like a moral concept and cause-and-effect sounds like pure logic, they both teach us the exact same truth:

We are responsible for our outcomes.
Conclusion:
Therefore, to ensure our effects are positive, we must control our causes. We must choose to be prepared, do good for others, practice humility, and have the courage to make changes before a poor choice turns into a permanent regret. The best way to predict your future is to act wisely right now.
