One thing you can try is playing a bunch of STTs. They're not the same as an FT because everyone starts with the same stack. The payout structure is different too, but maybe not as different as you might initially think since MTT payouts are usually top-heavy. Also, if you play 9-or 10-man, there will be stack size difference once players start to bust, so that there will often be stack differentials to consider after a while, similar to what you have right from the start of an FT.
I partially agree with this person. The first thing you should do is read strategy articles, like the one in the second thread comment. Once you understand the strategy and want to practice it (since making the FT of MTT's isn't something a person does "all of the time") then begin playing single table SnG's. This will allow you to practice adjustments as players drop out and comparatively to your own table stack. As said above, there is a slight difference between it and your average FT since stack sizes all start the same in STT's, but it's not enough of a difference to discourage the practice. Also, once you get good at that, you will have to learn how to continually adjust to less and less players (because to be successful at shorter handed you must up your aggression and expand your preflop hand range). To practice in this manner, practice with 6 handed SnG's and Heads Up SnG's. As well, read as many strategy articles as you can and watch some strategy videos on youtube (just search keywords:
poker strategy). I'd recommend the
wsop Academy videos, but anything by a pro is normally good. Also, find a video that fits your style. For example, if you are a tight player, watch Helmuth's videos, loose player, watch Gus Hansen's, etc. Find ones that fit your style, or how you prefer to play because you shouldn't change your own comfort levels in the beginning while still learning.
