"Il vaut mieux faire quelque chose que vous savez pouvoir faire mais que la plupart des gens pensent difficile que de faire quelque chose que vous pensez pouvoir faire mais que la plupart des gens jugent dur"

Simplified Meaning:

It's smarter to do something you're sure you can handle, even if others find it tough, rather than trying something that you find difficult and others also think is hard. For example, imagine you're very good at fixing computers, but most people think this is a complicated task. Instead of attempting to climb a tall mountain, which you think you might manage but know is challenging for everyone, it's better to stick to fixing computers. This way, you're playing to your strengths and will likely succeed, even if others think it's impressive. It's about focusing on what you can confidently do well rather than taking big risks in areas where both you and others see significant challenges. By doing this, you can build your reputation and skills without the fear of failure.
