I think intimidation is a large unspoken obstacle in bonsai, as it is in learning any new sport/activity/hobby.
I used to teach skiing a very very long time ago.
Lots of beginners had it firmly in their minds "not to fall" on their first lesson--some perceived falling as some kind of idiot move that marked them as uncool. Others were afraid of getting hurt. Falling on your first lesson--or fifth, or as an instructor, is part of the activity. It happens to everyone. Fearing it can add to the damage.
I learned that folks either learned to laugh at that fear and manage it, or they never really got over the perceived indignity of falling and quit. BTW, some even said falling was MY fault for not teaching well enough--never mind all that complicated gravity/physics stuff. I learned the best students weren't all that afraid of falling or making a fool of themselves, if it meant they actually learned how to ski. They learned HOW to fall to avoid injuries...I also saw people who were overly intimidated and scared of what they were doing get some fairly bad injuries fighting a fall. I also saw those who were overconfident of their capabilities, or dismissive of the challenges of advanced terrain and instruction, get badly injured too.
Take from this what you will, but being intimidated CAN be an impediment. It can also be a tool. Don't let it stop you. Learn how to fall with some style and understand why you did.
