"Quand vous croyez en quelque chose croyez-y totalement implicitement et sans réserve"

Simplified Meaning:

When you have faith in something, it's important to trust it completely without any doubts. Imagine a time you believed in a friend's ability to win a race. If you trust them fully, you support them wholeheartedly, encouraging them and helping them train, never second-guessing their chances. Doubting regularly can shake their confidence and yours, making it less likely they'll succeed. In life, when you put your whole heart into something, be it a goal, a person, or a project, you're more likely to put in the effort and stay committed, making success more achievable. To apply this to your own life, pick your goals carefully and then dedicate yourself fully, avoiding any negative thoughts that can lead to failure. This firm belief fuels persistence and can help make your dreams a reality.
