Can someone help me to understand the Saturn-Mars situation in my birth chart?

My Mars in Libra is conjunct my North Node, while Saturn in Aries is conjunct my South Node. Moreover, my Ascendant is in Aries. I think this has manifested in my life as a lack of discipline, procrastination, and an inability to finish things. But I'm not an expert. What do you see? How can I overcome this difficulty?

Thank you very much.
