I think I suffered from being drawn into apologetics without having the proper foundation of "why" we give an apologetic. Without a proper foundation it is easy to be focused on making points and better points to bring someone to see the "irrefutable" prove of a position, this leads to great frustration as this someone continues to reject the obvious, but this is because one began with the wrong foundation entirely. Our apologetics must begin with a focus on "one audience" ...only-- the Lord. Is the Lord being glorified, praised, honored, pleased in this apologetic. Am I humble, prayerful, meek, loving, diligent, serving, sacrificial, encouraging, friendly, forgiving, forbearing, patient, kind in the apologetic. If we provide an apologetic in faith, and with a single-eye upon providing it as an act of thanksgiving and worship to the Lord then our foundation will be proper; and frustration will not develop because we will not look to earthly results in our offering which is heaven-ward.
