I checked your
sharkscope profile, and on
pokerstars your average buyin is only $0,13 over 1.125 games with the last 8 games being
freerolls. I cant see any more, since you did not opt in. Given this playing history my main advice is to forget about MTTs, that last more than 3 hours, until you have build up some sort of
bankroll. Focus instead on either cash games and SnGs, where you have much more flexibility to come and go, as you want to. And also a much better chance to reach the top prices (in SnGs), since you dont need to outlast 2.000 other players to get to a final table.
My other advice, which might not apply to you, is, that any kind of serious poker has to be played from at least a laptop or tablet, not from your phone. A phone is for playing a Spin n Go or something similarly fast, while you are riding the train to work or sitting in the airport and waiting for your plane. Or maybe a hyperturbo freeroll, like the ones you have been playing lately on Stars. But for serious games you want to have a larger screen, so your eyes get less tired, and so that its much easier to multitable. This also helps to keep boredom away, as tables will constantly pop up and require your attention.
