One hurdle people should learn to break is the beginners hurdle. At the beginners stage alot runs through your head(is this really my thing, can I keep up to the standard, goodness me there are too many intelligent people here) the self discouragement is high at this level.
But all that's needed is that push, that boldness to get to do it.
I as an example from a 3rd world country I heard about bitcoin early 2017 but it wasn't anything elaborate not until last year when I enrolled for a lecture and was aware about bitcoin I was really interested and my to cut a long story short my question asking and research lead me here.
I believe what a newbie should think of mostly when here is how to improve themselves no matter your high or low tech skill(all that should be put aside). Never be scared to make errors and most importantly be willing to follow correction.
