1 - Think about someone you love each time you want to be productive that will boost your imagination to the roof.
2 - Take time when you think, from time to time we fear to take 10 min an think about anything that give us emotions or motivations.
3 - Notepad or a Filler Paper can be you best friend, but he don't keep secrets
Just take and overload those papers like you have never before seen a Filler Paper ( release you ideas make your brain more able to think more).
4 - Use music as your feelings stream, I listen to all kind of music but I got a great soundtrack that makes me get active and improve my brain thinking and working cycle, also work more than I do the whole day just in one hour.
5 - Drink water a lot, do sport and take care of your health.
I got more but these are my main stuff I personally do.
