Starting in poker

What was your biggest difficulty when you started in poker?

Those who have been at the tables for a long time, your answers can give beginners a guide.

frustration, managing emotions, and as a beginner you run a great disadvantage if you start playing without much knowledge and without study, in my case it was like that, I remember that I played all in JQ things like that, I didn't know anything about positions, etc.

Build a bankroll and dont loose it all playing out of my limits

biggest difficulty was not to hury to win tons of cash, its a step by step work
