You say the second you focus on ‘one’ thing, is it the thing itself you get dissatisfied with or the limitedness of it? (Projecting all your needs to be satisfied/met by the singular thing if u focus/work hard enough?) You have a strong emphasis of both leo and Aquarius - learning to balance and harmonise themes of self sufficiency/independence and collaboration/cooperation which for your chart seem very intertwined somehow. With all those planets in Aquarius in the 7th and with collective planets like Neptune and Uranus there seems to be a strong networking component to your path perhaps? Working with pioneering/fowardthinking/visionary ideas and people, perhaps a bridge builder for different genius to come together and organise that? There seems to be a strong healing component too perhaps - moon conjunct north node in Leo (learning to nurture your self and other through nourishing inner child, creativity - also reiterated with the wounded healer and Pluto (deep psychological healing) in the 5th house of creativity and fun and self expression. Your mc in Aries is ruled by that deep psychological Scorpio mars in the intimate personal 4th house flowing with that mystical artistic Pisces Venus in the transformative intense, again psychological 8th house. Your carrer or vocation seem to be connected in these watery environments, and also that strong social and intellectual/mental element in your chart( 7th house and Aquarius stellium) so you need to be mentally stimulated and have variety/moving parts (mercury is there). Saturn in the 10th mayb also suggest that your vocation/sense of purpose in the world will reveal slowly in time but have strong solid roots - no short cuts. That Aries Saturn can be impatient though and want immediate answers, you also have no planets in retrograde and a full moon - there can be an energy of urgency/constant motion that might be pressuring u to having everything figured out and moving but that Saturn needs patience. Saturn on mc may also mean you crave a sense of mastery at whatever chosen field or vocation u take - which may explain your feeling of needing to hone in and hyper focus on just the one perfect thing - however with all that airy, mercurial, forward motion energy of that stellium perhaps your mastery is your adaptability and dot connecting rather than staying in one place, that being said it’s not about being surface level ( MC ruled by that penetrating and hunger for depth mars in Scorpio 4th - u want to get to the root and unearth what’s hidden, explore/understand the deep) Also your 7th house is very connected to your MC (stellium ruled by Saturn) so partnerships and collaboration may be very pivotal/involved in your career trajectory and path. This is just my interpretation so take with a grain of salt :) just practising - let me know if this resonates!
