I don’t know if you are still trying to do this but if you are, here’s an exercise to try.
Look at an object and draw it without looking down at your paper and without lifting your pencil. Try to just get the outlines and don’t worry about shading or proper size or perspective. It’s fun and freeing.

Also, I always used to try to draw “too tight” with too much detail. Every drawing was painstaking and took forever. Doing pen and ink with a fountain pen or a brush and purposely being minimalist helped me break this habit.
