It all depends on the perseverance and patience you have.
Learn from those who know the most.
Take into account luck that also exists although poker is a game of many probabilities.
Learn not to get mad over a badbeat.
You won't always win with AA or KK in hand.
Well many things you will have to learn in the process.
And as a friend said above, little by little you should increase your bankroll
Keep in mind that because you win an MTT of US$50 you should not get into large tournaments, but consider that if you have US$50 bankroll, you should access a maximum MTT of US$1, no more.
If you learn to play cash tables, do it at low levels, but don't be tempted. It is better to play MTT or sit & go.
Some tips friend.
If it works for you, search on youtube for Zeros poker's career, he told his entire career from the beginning. It's very interesting.
Greetings friend and success
