I'm going to agree with Luvepoker above let's just slow down on the live MTT play. You say you play online and that's good you can gain a ton of experience/volume at very cheap price compared to playing live poker where you might 30
hands/hr(you probably won't) likely to be more like 25 hand/hr. And yes experience matters and by double tabling 6 max online you can between 130-170 an hour.
If I were you I'd deposit $50 and start at 2nl......6 max and get confident, good enough and comfortable enough to last double table. If/when you can turn that $50 into $500 playing 2nl-5nl cash on the weekdays and micro stakes buy-in MTT's on the weekends. Then you you're ready for live MTT poker and you earned your first buy-in part of that $500.
Till you reach that point study MTT poker, ICM and short-stack re-raise and all-in preflop charts. Also I'd recommend reading a book on live poker
tells most them are older books now but if nothing else it will put you in the mind to know what to be thinking about while sitting at the table live. I used Google and the newest top listed book if here
https://www.amazon.ca/Reading-Poker-Tells-Zachary-Elwood-ebook/dp/B008MIM90Q .....Here's the one read way back in
https://www.amazon.ca/Phil-Hellmuth-Presents-Read-Reap/dp/0061198595 . I haven't read the book in the first link. Fwiw there's a bout 6 years difference in when they were published.
EDIT: Live poker is most the time is pretty boring....if I was too give you one piece of advice always be studying the other players and everything little move they make and even how they put their chips into the pot. Also never look at your cards till it's your turn that way you can't give anything away unknowingly too the other players. What you should be doing while the cards are dealt is watching the other players the moment they look at their cards. That's the best time to get a real, honest reaction and tell from them in that very second they first look at their cards. Pay attention to villains that have position on you......if they seems uninterested in their hands/cards then you are now playing from a stronger position because their folding. If you're the 3rd player from the button and notice the two players behind you aren't interested and have shown signs of folding congrats you can now play your mid table position like you are the button.
Best of luck with your poker journey.
Cheers!!!
