Don't be afraid to do things
Well as you know i am building my own version of what I think markdown should be. What I mean by this is just because a solution already exists doesn't mean you cant build your own.
You only get better by doing the hard things and only when you understand what's underneath does your understanding change it may not mean all your projects may go the way you expected them to but at least you learnt something along the way and you now use and appreciate the tools in a different light and maybe you can take a stab at pointing out and contributing to fix the flaws of much more established projects
I'm not really someone who writes much so I am sorry if this isn't up to standard
