My biggest reasoning for not babbling is imposter syndrome. So there’s no better exercise than this to start babbling :)
Read a book on imposter syndrome.
Meditate
Talk to someone
Cut yourself some slack
Read about babble!
Ignore it and publish the result anyway
Look at your past achievements
Do a poll on twitter asking how many people get imposter syndrome
Sleep
Go do something you know you’re amazing at
Write about your feelings—writing therapy
Enjoy it until you have it.
Get a coloring book and color inside the lines. That’s hard!
Cook something delicious
Listen to some motivational/self-help speaker for some short-term boost
Go for a walk
Do some intense workout
Laugh at yourself
Take some time off and have some fun
Take a crazy cold shower or better yet, an ice bath
Watch batman take on the Justice League
Help someone less fortunate than you
Dance
Take it out on a punching bag
Do some kindness meditation
Maintain a streak of how many times you overcome imposter syndrome
Break it down to identify the underlying reasons, and solve them one by one.
Join the army.
Do something you think you can’t do.
Go for a therapy session
Get out of your room and surround yourself with nature
Watch an uplifting movie
Have sex
Go to a coffee-place and chill out
Go for a hike
Pick something else, and come back to your current activity later.
Pray to god
Talk to yourself and increase your self-confidence
Ask someone to take a look at your paper—you’ll probably hear that it’s not that bad.
Hangout with someone
Sit by a river/lake/sea
Play with some animals (puppies?)
Talk to someone who you know is an imposter
Act like a real imposter and fake something. You’ll realize you weren’t being an imposter earlier.
Read psychology
Buy a block of cheese and slowly enjoy it to its fullest
Do a r/roastme
Sing your favourite songs
Go to a language club of your native language—feel like a king.
Don’t do anything. Sit there and notice when that feeling passes away.
I’ve been thinking about this too, and I agree with your conclusion. The way I think about boredom is that since we (or the environment) block off external stimulation, our mind is forced to internally stimulate us (assuming that we have a constant need for stimulation).
Initially, as you mentioned, this leads to remembering small tasks and worries that have been on our mind. But after exhausting that reserve, it has no option except to stimulate us with things we haven’t been thinking about consciously, i.e—creative thoughts.
I’ve been failing to implement boredom as a habit, the closest achievement being meditation. The failures have been mostly due to finding new excuses and persuading myself not to do it “right now”. But am curious to know how you’ve changed your actions after this.
