Professional vs Recreational
The assumption that becoming a dive leader will make you a great diver is false. What makes someone an expert in diving is education and experience. The true difference between a recreational diver and a professional diver is the want to teach and lead.
In order to join the ranks of professional divers, you must be willing to take on massive responsibility and ready to sacrifice just as much. Once you become a leader, you'll be responsible for everyone you dive with whether or not you intend to be. For example, if your buddy breaks their depth limit by even a foot on a fun dive and has an accident, you can be held accountable. You'll also be expected to lead by example at all times. It also means you have to follow standards and procedures to the letter and do everything possible to prevent others from violating them.
The added liability and responsibility can be worth it. Sharing the wonders of the underwater world with others is rewarding, but you have to have the desire to do so. There's nothing wrong with staying a recreational or technical diver. Do you have the passion required to become a dive leader?
