Set aside specific times and stick to them. Do you prefer to cover ground to learn in depth? If you enjoy covering ground, set yourself a goal – an omud a day? Half an omud a day? Work out a realistic plan for how long this will take, and dedicate that time for learning. If you enjoy learning in depth, don’t set a goal in distance, this will only disturb your goal. But dedicate that hour for learning this particular limmud, and stick to it. If you have a specific time set aside daily for one activity, it is much more likely to be accomplished.
When it comes to Halachah – especially Hilchos Shabbos – it is very easy to give up. Again, keep a specific time for Halocho, and try keep to schedule as much as you can. If you can commit to a page of Mishna Berura daily, you will cover ground. The key is to be as diligent as possible, because when it comes to Halachah, if you miss your seder once or twice, you will find you are getting nowhere and give up. It’s got to be persistent, determined and diligent.
The key is in the decision. How much importance you give the limmud will be reflected in your decision to simply learn. Keeping a seder is easier than learning when you have time. Make sure you have a structure.
