First of all the most important thing is that you allocate the time for your practice. As you probable know this saying: practice makes the master. As everything else in life, you need to do something to achieve something. Don't think that without doing the qigong exercises you can have the benefits.
This was said to the general public - of course you don't belong to the, do you?
So let's go deeper. If you fully want to take advantage of your qigong then you must have ashedule. That is you must have it planned, programmed if you wish in your everyday life. You can see great results if you stick to that program.
Also remember to wear comfortable clothes while doing the qigong exercises. The best practice is to do them in the same set always. The energy adds together and just by putting those clothes on you get into the right mindset.
Sometimes it's easy to do them while at other times you just come up with all kinds of "excuses" - your body wants to opt out for whatever reason. What usually happens in these cases is that the energy in unblocking your meridian. Keep on doing the posture and in a couple of minutes the discomfort dissappears and leaves you wondering how easy the practice is again.
