Learn Dynamics 365 by actual business needs.

Hi all,

I am currently learning to be a Dynamics 365 functional consultant all by myself. Basically, I had go through some of training but it appears to me that I only know the dots, not yet the connection between them to apply to real life business. I would appreciate if you guys can share with me a road map to learn how to implement a Dynamics 365 system with business requirement. For example, what i need to know to configure for a medium size company.

I am sorry in advance if my question is too broad or vague or even stupid. Thank you and have a nice day.
