Thank you arthurbentley for sharing your tips 
I'd like to add my opinion on them, because I disagree slightly:
I would not recommend splitting your bankroll at this point of time. You should really focus on one site and one structure and try to get good at this one, before moving to other adventures.
FTP is worth a look - but imo that's about it. Sure, there are a few valuable tournaments as well as good structured (rake wise) mtsng's. Problem is, that there is substantially less traffic and way more good players on average. Therefore I wouldn't suggest playing FTP at this point in time.
Furthermore I wouldn't suggest 18men mtsng's. Yes, the variance is a lot smaller! Downside is, that ICM is way more important and really fundamental. Imo that is not a good idea when you start your poker carrier. Furthermore you won't be able to achieve a ROI that is nearly as good as the one you might achieve with 45men or bigger mtsng's. Lastly they play pretty much like a single table SNG and they don't have much in common with normal MTT's. If you consider playing MTT's in the future you should practise them - and therefore not play 18men mtsng's, but bigger one's.
Same thing with the single table SNG's obv. Low ROI, not much in common with MTT's and more difficult to play then mtsng's.
From my point of view, Acespeci took the right choice with playing 45men mtsng's. It's a good way to go. However, this is just my personal view. Feel free to ignore it and play whatever you think is best for you - this is most important. You have to feel good doing it. There is no point in playing something which doesn't feel right for you, solely because someone told you it's best to do so.
@arthurbentley: Please don't take this posting as an offense or even critic on your posting. I really appreciate it if players give tips to others. I just want to state my opinion and hope it might help someone in his or her decision making process.
