I think that with meditation the best thing to do is to just practice irreguardless of the outcome. Practice makes perfect. So when you have those days that you just don’t see the point than all you can do is to just suck it in and complete the practice of meditation. Practice, practice practice!! Practice makes perfect. Too often in our society we want the quick fix, we don’t want to believe that things and skills can take time to develop. We just don’t want to see that it is bold determination that so often rules the day in any endevour and if you desire to get something out of meditation than you must, yes indeed you must endure even in days where you don’t see any point to continue.
