How can I make Strong like me without compromising myself?

The wiki says Strong (and I have noticed that Curie and Hancock as well) likes to be out and kill things... And that gains approval even if it does not seem that way. Allow me to elaborate; you can get strong to adore/idolize you simply by going out, exploring and killing. So you do not necessarily need to do things your companion "loves" or "likes" for him to gain approval. I can confirm this is true for Curie and many people seem to agree it works for Strong too.

So my suggestion? Go to Diamond City, check the bounty board (that's left to the guy selling "swatters") and do a lot of them with him. Most bountys just requiere you to go somewhere, kill the boss of the place and loot. So do that, but remember never to lockpick.

What I am trying to say, is that the following is without logic, but still happens: I left Codsworth at Sanctuary, and you notice that he "loves" when you customize a weapon or an armor, and so I intentionally only customize things at Sanctuary to have him "loving" it, but how can it be that it took me 8 "loves" just to reach the first level of approval, and with Curie i have barely got one love and 4 likes and she is already in 3rd level of approval with my character? Well it seems that "hanging out" and "watching each other's back" raise approval silently. So you most definetelly want to take strong with you to some raider camps and gunner strongholds. He will "approve" just being there as a team teamwork. I hope someone with PC and console commands may explain how does this works (because it does) in terms of how much time spent, or xp gained, or enemies killed it takes to get "likes" equivalent approval... But that's that.

If you have trouble finding the bounty board, go to the mayor's office and ask the secretary for work. The bounty board will appear on your map after that.

Strong likes it when you help settlements for the Minutemen.

Believe it or not, Strong likes it when you do settlement building. I brought him with me to carry some weapons from Sanctuary to Castle, so I could glitch the settlement size meter. I had not done any actual adventuring with Strong, he was just my mule.

So I did the glitch, and proceeded to continue working on my Castle build. Strong just stood over by the workbench the whole time (which was nice cause he was out of my way, unlike the settlers that just walk right through my build), anyway...

It wasn't long before I see "Strong Idolizes You" on my screen. So I went to talk to him and BAM! Companion Affinity Perk unlocked.

I got the "idolize” caption for Strong just after having a doctor, specifically the one in diamond city, heal my radiation. I can't say for sure if that was why, I haven't read anything anywhere for that helping, but I had over 50% of my health bar as radiation damage so for $40(caps), You can try it. And thanks to everyone posting and giving input on any site, You all rock!!!

the key for me was to save and load. had him with me for awhile and a lot of likes and dislikes from strong, but after the load up strong wanted to talk and gave me the perk. so if you've been playing with him as a companion for awhile and you have not received the perk, try saving your game then loading that game again.

I had him go with me to all my settlements and carry supplies for me. He suddenly idolized me when we returned back to the Castle. I believe it's the human kindness thingy he's always talking about. I also gave him a ton of ammo with a minigun and let him do his best.
