For me, determination is harder to muster when something aimed for, is not meaningful or has no purpose behind it or cannot be related to or is not high enough on my list of priorities. It is easier when the rewards or consequences are more visible and immediate eg getting up early to get to work on time (no matter how tired) to earn money.
It is not so with other things eg meditation. Meditation is more based on trust and faith of benefits not yet necessarily felt or the truth of life and existence not yet experienced. This is fine during a retreat (with the environment, teaching and atmosphere) but soon after – the determination starts to ebb away, as the rest of life’s demands rush in. For the meditation, I would like to maintain the determination and discipline but somehow I have to make it of greater value than anything else and embed my learning into everyday living.
