There are a couple of rules I set for my creativity.
The rule is I set aside 1 hour for a blog post daily and sometimes that blog post takes 5 minutes and at other times it takes 30 minutes. I still give myself an hour to create a post regardless how long it takes.
I gave myself a rule the other day for when I am working with video. I told myself that every vlog post video I create will need to be shot and edited on the iPhone. This pushes me to not have any excuses for not creating. I have produced 6 vlog posts in the past 2 months all shot and edited on my phone.
I got back into reading music this past month to create my own music for my vlog videos and the rule is that I eventually want to create all sounds from scratch. No audio libraries to download from as this will create a unique piece from scratch.
There are more rules I plan on setting so I can have limited access to tools, ideas and processes. This will spark creativity.
