Heretics usually fall into the role.
Seldom does a man wake up in the morning, grab a cup of coffee, read the morning newspaper, put on his clothes, and then stare himself in the mirror and say “Today, I shall become a heretic”. Heretics usually start by staring in the mirror and saying, “Today, I shall be a difference maker”.
Consider Sabellius. Sabellius became what is now known as a modalist. He was deeply concerned with maintaining the biblical truth that God is one. He also wanted to maintain the biblical truth that Christ was fully God. These two truths seemed to Sabellius to be neglected. And so he re-emphasized those truths but whilst doing so neglected another important truth; namely, that God is three distinct Persons.
Tertullian responded to the modalists by clearly showing how Scripture presents “one substance consisting in three persons”. But Sabellius was unmoved in his position. He would eventually be condemned as a heretic in 220 AD.
His story is not unique. In fact most who find themselves outside of orthodoxy follow a similar pattern. You can see this same trajectory even in our own day. So if you want to fall into the roll of becoming a heretic here is how it will likely happen:
Step One: Have a desire to be an epic difference maker.
Step Two: Find a truthful doctrine that is being neglected or under emphasized
Step Three: Make your ministry about restoring this precious doctrine.
Step Four: Begin emphasizing this truth to the expense of other equally true doctrines.
