The added urgency will help you feel motivated to have it done. Reward yourself when you have successfully completed a high priority project. Instead of thinking about what you didn't get done, recognize all you did get accomplished and reward yourself for having done the most important things. You will learn just how much you do get done. Practice self determination, wanting to do it for yourself.
Nothing takes the place of persistence.
Believe that you can be what you want to he. Operate on the philosophy that what we give out is what comes back to us. Occasionally, sit quietly and do a self-assessment of your skills and strengths. Praise yourself for your progress. Recognize not all days will go as you desire.
