Most of the time I am at low energy (maybe because I have bad sleep, I dont know) and when in low energy, being mindfull is a damn pain. I must have energy and a fresh mind to be delighted with mindfulness. So, my advise is to have energy! I would like to read more advises and ideas here because mindfulness is such an important thing. For example, sometimes I get tired with being mindfull while doing daily stuff, how can I fight against that?
At last, it would be great to if you could find a retreat where you can learn more or, at least, be in peace. I would like to find one, but that would mean to abandon my lay life.
Same experience here. I think a lot of the fatigue comes from habitual hamster-wheel mind, like bouncing your knee until it gets tired. Or you may have the bad habit like I do of thinking yourself into being more tired than you actually are! I have to ask myself "says who?" all the time, and the results have been surprising.
Viewing mindfulness as a sort of rest into what's already there instead of energetically generating a new state of mind helps, too. Mindfulness can be very gentle and restorative, just noticing sounds for example instead of how tired we are. Seems like we can make a trap out of anything.
You may also be conflating concentration, an active willful process, with mindfulness, a receptive noticing process. I may be wrong.
