The only way to improve our lives and to improve our work is to take time to work on ourselves. Our work is our reflection. If we are angry it shows, when we are depressed it shows, when we are in love it shows, etc. We have to improve ourselves as our work typically willimprove once we discover who we truly are. You have to be consistent and you have to be courageous.
So even if you are afraid you must still act. Open up a book, sit at your desk with your electronics, go take a walk. Take the time to ask all the important questions if you discover something then quickly act before your motivation falls flat. Go out there, improve yourself and naturally so will your work. But it takes hard work and a ton of practice in the dark to truly improve.
