Listening to podcasts and working with other people are distractions.
Listening to podcasts requires attention, because someone is speaking and a part of you is trying to listen and understand what this person is saying, which disrupts your thought processes. It can be ok if you do really basic work which does not require important creative decisions.
Working with someone else also distracts, though it can be good to have someone to bounce ideas off and to ask advice.
what you need
- a sense of accomplishment, to give your brain a much needed endorfin boost. So break down your work into small tasks that can be finished in no more than a day or two, to have that regular confidence boost.
- a sense of purpose. So you need to feel really excited about your project. Maybe you don't. In that case, inject your project with something you can feel excited about. A creative or technical challenge that offers you a learning opportunity so that, even when you do boring or repetitive work, you know you are getting something out of it, not just going through the motions to get it finished.
- an undisturbed thought process. Like bad sleep, constant interruptions to your thoughts keep you on the surface. Your ideas, solutions and work stay shallow because your thought process is interrupted every time before you have a change to really think things through.
- when you have problems starting something, start small. Very small. Psychologically the barrier is very low in that case, so it's easy to actually do it, and since it was fast to do, you have quickly that boost of accomplishment that makes you feel excitied to continue.
- do not look to much and long at other people's work for inspiration. Soon, you'll do nothing but inspiration gathering and your project lies abandoned. Look at some nice work, copy what you like in some colour sketches, and put the inspiration away. Then, start working from your sketches. Or else you'll never do anything nor find your own voice.
