Set very small goals. Practice every day, even if only for 5-10 minutes. If you have only 5-10 minute, pick a very, very small goal - playing a scale very slowly and with relaxation. Learning 1-2 measures of an easy piece. You'll have years when the pressure of work is off and you'll have more time to practice, so right now a consistent little bit each day will get you going. In fact, I think that at the beginning, logging lots of time is not all that helpful. Just learn to make the correct motions, and practice only the correct motions for a little bit every day.
