A starting point for a follower is humility. It takes humility to realize you don't know where you're going or how to get there or what to do on the way or when you arrive.
Truth be told, the best leaders are also humble, recognizing that what they know they gleaned by following another and what they can share or do isn't everything that's necessary.
I pride myself on having a good sense of direction. I have used that to get myself, my family, and my friends lots of places. Most of the time they seem to appreciate it. Sometimes they seem to be annoyed by it. My friend Michael has, for 8 years now, relished the time in Atlanta that I went the opposite direction than we should have gone (he was certain we needed to go to the left, I was equally certain we needed to go to the right; he was correct and hasn't gotten over it). A wiser me would realize I don't know Atlanta's roads at all and would have been humble enough to seek assistance.
So, a first step toward being a good follower is recognizing limitations and being willing to observe, ask, and learn (often by doing what the leader is doing).
That willingness is increasingly difficult when the leader is doing something (and asking you to do something) that is contrary to what you want. Jonah was led to go to Nineveh to call that city to repentance. He went the opposite direction, not because he was lost, but because he didn't want to fulfill his calling.
The disciples' immediate response to Jesus' call resulted in some amazing successes as they were learning the ways of Jesus and some failures as his ways asked of them more than they sometimes wanted to give.
I don't know if you are ready to go to a modern-day Nineveh and tell them God loves them and wants better for them, despite their wicked actions. Maybe loving your enemies by praying for them is the best that you can do today. But, as Jonah and Jesus' disciples learned by finally acquiescing (Jonah) and by following (the disciples), going to another is the best way to love them.
If you are struggling with loving someone because of perceived differences, the call may well be for you to pray for him/her, then get to know that person better. It's the kind of thing Jesus did, so it's the kind of thing his followers should be humble enough to learn to do, too.
