Why can I never finish almost anything I start and never know what I want?

Jupiter square Sun is usually an overapplication of Jupiterian expansionist energy. You probably have a lot of ideas and start them all and have a million things you want to try. 
Another aspect is Moon square Venus. The Moon represents emotions and instincts while Venus represents romantic emotions, aesthetics. The square means they want incompatible things where you must balance your needs. This likely plays out most visibly romantically where your Cancer Venus wants someone kind gentle nurturing, but your Aries Moon wants someone exciting bold kinda an asshole/bitch, similar to your Mars in Leo is drawn to flashy/strong arrogant types
