1. What is the best step a beginner should know and do, to become better and more successful like the friends here who have been working here for years.
2. What is the percentage level of difficulty for doing something good here.
Less talk less mistake. What I've meant is if you are gonna be a long time user here in forum. Customed yourself into reading good posts. Also don't just comment or response to such topic, read what the current discussion and read their opinion, and when you grasp something is kissing then tell what you think. Forum is all about opinion and discussion, but with a conservative method for spams.
Goodluck on your journey here.
