Ok 1st thing, your GPS is not showing a heading. It is showing a traffic across the ground usually in magnetic but that will depend on how you have yours configured. Of course your track will vary with current, winds and your leeway. Also your compass needs to be calibrated for your installation area (deviation) and it is also subject to magnetic variation. So it is no small wonder there is a difference between the 2.
If you always put limit on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
