Why do we sit daily? 

What does it take to have a daily practice?  What I have noticed about daily meditation is that it is helpful if there is a clear aspiration or intention and also support and accountability.  I know for me my wish for myself and for all being to be free and liberated helps me get on the cushion and meditate.  I may not always feel like meditating but when I can connect with my aspiration I am motivated to sit.

What is your aspiration?  What do you hope for by engaging in your meditation??  Answering those questions may really help you in staying with your practice.
