Not my area of expertise as I tend to shy away from strict schedules; but I commend you on your intentions. Be sure to keep a lid on your sense of self doubt/blame, they can be powerful motivating factors when controlled but can have the opposite effect if they gain control of you. I’ve always found it good to remind myself from time to time that my choices have brought me where I am as much any circumstance and it will be my choices that lead me where I want to go. Remember you are in control. Don’t forget to reward yourself from time to time, particularly when overcoming difficult or conflicting tasks. It will help reinforce your effort and attitude. Be prepared for failure, it will happen, just don’t stop and dwell on it – learn from it and move forward towards your goals. Be sure to take a second and embrace the moment as well, stop and recognize that your are accomplishing something even if it’s just research for a class, a menial task for your job, or rote practice for your music. It can go a long way to keeping your mindset positive and providing a sense of fulfillment. Best of luck to you, I hope your commitment is rewarded.
