Hi. Yes Sun in the 10th house can signify this, but there are also other relevant placements in the chart. Placements that jump out at me are:
Moon in the 2nd house, which may struggle to feel secure because conjunct Chiron in Scorpio. Note that the 10th house Sun is ruled by the Moon in this chart.
Mars also in the 10th, and in fact right on the midheaven.
The 2nd house Chiron aspects the Sun and Mars in the 10th.
Virgo rising, with Mercury in Leo ruling Venus and Mars.
Uranus makes some important close aspects, suggesting a need to contribute something to the 'greater whole'.
Saturn closely square Neptune (seeks redemption through assuming a position of authority or responsibility, but the high level of idealism means that there always seems to be something lacking).
You might want to reduce the orbs to about 70 or 80% to get rid of the wider aspects. Best wishes,
Miquar
