If the work that has to be done has a deadline, and you find yourself procrastinating right up until the deadline, whereby you work frantically on the boring work for far too little time but still manage to get it done - I wouldn't worry so much yet. In fact, if you can gauge your ability to get things done at the last minute, and you've sussed that you only work well under extreme pressure, you can enjoy your procrastinating and schedule in the real work for the last minute. I don't advocate this for a life strategy but it sure got me through undergraduate maths supervisions.
