It is a dreadful thing to have writer`s block once in a while, isn`t it? Ideas that won`t seem to appear even you tried your hardest to think. Colors, feelings, patterns, and shapes, nothing comes to mind.
You tend to indulge yourself in exercises that may help you get that creative engine up; however, you feel that it is not the right thing to do. You pressure yourself into a state of pure imagination until it falls down into submission.
Stop, just have a moment to stop thinking, grab a bite, listen to tunes, and put yourself in a state of calm. In time, you will see the different branches of ideas sipping what is rooted in your inner thoughts.
Give yourself a break, Never give in to the pressure.
