What hinders me ... nothing.
Well there is one thing of course, the only thing that actually hinders every photographer: No light.
Other than that, nothing really hinders me ... anymore. Between the start of this thread and now there was a masterclass I took and grabbed a piece of advice to a specific subject and recognized this as concept for my entire photography and I ran with it. This was about 2.5 years ago and still works for me.
Find a teacher, a master, be open and sensitive and filter what applies to you. Sometimes it's a small idea that literally breaks down a wall that was hindering you. Your photography and you as a person.
Obviously it's difficult to find the right master and you'll only know afterwards if you wasted time and money. If you don't try, you won't find out.
I was lucky enough that it just clicked for me.
