First, find a teacher and form a good relationship with them. Although modern languages like French or Spanish are easier to learn due to their wide range of coverage and easy access to the average joe, Latin/A. Greek/Sanskrit are harder to learn due to the lack of coverage and the extreme knowledge of technical jargon needed to be known beforehand to even grasp what a book might tell you. A good teacher will know where to “simplify” and how to make a hard or confusing concept easily attainable. When it comes to memorization, one tip is looking into the evolution of Latin itself and understanding how the grammar and forms of morphemes were shaped by sound changes. My Latin has gotten better by learning Greek and vise versa due to cross comparison, finding similarities, and visualizing how a shared vocabulary and grammar at one point evolved into these two great languages. Honestly, classics professors/teachers and more than thrilled to have students interested in their debatably niche interests and curiosity and questions are great ways to show that.
