You need to fall off to know why you shouldn't fall off. You need to fall sick to know why you shouldn't fall sick. You need to fall short on your goals to know why you shouldn't fall short on your goals. You need to taste bitter to know what sweet tastes like.
There must be some form of activity in one side for you to figure out the other side.
You won't know why you shouldn't fall off if you never fall off. Maybe falling off is the right approach to living life you want. Maybe you only find hidden treasures when you fall off.
Once you fall off and know the consequences of it will you only know why you should or shouldn't fall off.
You need to fall off once to know the consequences of it and if you should or shouldn't fall off.
The best example I can give for this is of people's perception about comfortable life. Most people want to live a comfortable and safe life in their comfort zone. They don't want to move out of it or push themselves forward. They are afraid to move forward because moving forward for them literally means falling off.
The irony is that, falling off is where you'll find the biggest joy and happiness in being human. If you don't fall off, you'll never get to experience the deepest joy of being a human.
You move forward only when you push yourself out of the comfort zone.
In the above case, falling off is a good thing. You'll move forward and improve yourself overtime.
We should always know the consequences of falling off. But we will never figure out the consequences until we fall off.
Hence, you need to fall off to know why you shouldn't fall off, or why you should fall off.
Until you walk the unbeaten path, you'll never know where it leads.
