Yes, I don't think it's the greatest idea to start out with builds, at all. Not unless you're a mechanical genius and willing to watch a LOT of videos.
Is there a reason you don't want to try something a bit less labor intensive first? I mean, you've said a lot of conflicting things here... You want it to be like a cigarette.... You want to have a hobby.... Maybe not such a good idea/oh it was great, etc.
You seem like you're in a *major rush* to me, which I don't quite understand? Is it because you said you may try 3 m.g nicotine if you're building? Sorry, just had to ask, since you did say it.
Slow down, dude. Just chill, already. Do things safely and progress up the vaping ladder like most people do. You aren't special, your situation isn't that special, you enjoyed your friend's vape set up (what was it?). At the very least, spend a few weeks learning to vape correctly and handle materials properly which isn't always as easy as it seems. Seriously, when I look in my crystal ball, today, I see a toddler clutching a bunch of batteries and placing them on the hot pavement while examining them with a microscope leaning over very far to check out the serial numbers.... LOL. No offense intended but sheesh, I have no control over my crystal ball, and your RUSH TO BE SO HOBBY ORIENTED AND COOL.... My magic 8-ball also says "Ask again later".
Then again, maybe everything will work out perfectly for you but why are you in such a rush to be the VALEDICTORIAN of the vape world? It's not necessary, and my assessment of the excited youth wanting to Be all he can Be (which is fine) should be tempered with some major research and waiting, while the adult waiting to burst out of the phonenix ashes is like, "Can you just chill already dude and let me vape in peace for a bit?"
That said, go read every damn thread in mods/building/battery safety and etc. DON'T just sit around asking random questions, you'll get your answers, but I doubt you'll be fully informed and you just seem like an accident waiting to happen. Maybe it's the language barrier, but CHILL OUT MAN OH BOY.
