This what actually happens to me. When I do try to concentrate in one particular work, I always do my level best to concentrate and working hard toward making a great output.
Sometimes, I decide to go far aways from people or lock myself in my room, and then starting my work. This makes my life easy since all my mind can be set to a particular task. At that moment, you only talk with your mind. I mean everything is just I and my mind. Sometimes, I feel excited, anxious or fully confident though wrong sometimes.
Forget about concentrating or working hard. Those things makes me too serious, then I loose the freedom of expression and fun of creating. The consequences of being serious makes your work turn out stiff and lack lustre.
Haha, sorry for meddling in here but you nail it! I also tend to say that whenever discipline is necessary, then the work is not fulfilling itself and external incentives become the main force that keeps us going. The entire process of creating is void of potential outcome, taking away any passion for our immediate surroundings!
I LOVE it! Thanks! :)
