If you really want to badly do it, then

Be patient with yourself, don't let frustration get the better of yourself, keep trying, get immersed and give yourself some time.

For me, it took quite some time of interspersed half-hearted attempts, then accidental and incremental opportunities to do increasingly complex tasks that I could learn and scale (on different environments, SAP, NC, Excel Macros, JMP), then some big time immersion over 4 weeks with David Power's books (his style clicked for me). I am no expert now, but am doing stuff that I didnt' think I could.

Would have to disagree about the "Natural" part of your comment. Keep working at it.

Good luck.
