One of the roles in my career is to help people get better physically. I do this by helping them get stronger, able to access the parts of their body they need to, and finding and correcting dysfunctions. I also do this through education. Just training people and telling them what to do gets pretty boring for both myself and my clients, and it doesn't allow them to have any control over their journey. I believe that people need to understand at least a bit of what's going on and what to do about it to be able to truly become better ("get better" is only temporary...I like long term solutions).
If your job is to help others, do so by teaching them, not doing it for them. Don't give them the answers, help them come up with the answers themselves. Don't just talk at them or tell them what to do, explain to them why they should do it. Help them understand the "Why" so they can correct the "What."
If you're concerned you'll lose clients because your turnover will be higher and you'll have to work harder to get more clientele, you're not in the business for the right reasons. Those people will recommend others to you if you did a good job.
If you're worried they'll have questions that you don't have the answers to, step up your game. Admit when you don't have the answers (nobody has ALL of the answers, nor should be expected to), but be proactive about getting them. This will make you better, too.
Help people be sufficient on their own. Help them be independent. Give them the power to take care of themselves.
Give a man a fish, and he eats for a day. Teach a man to fish, and you feed him for a lifetime. (Chinese proverb)
