When I saw the chart my first thought was that it was that of a student on the debating(Air significance) team at college/university. One who has a way with words in stating differences of concepts and definitely knows what they are talking about. Someone whose ideas
could make all the difference. Then I read the highlighted above.
Does this mean that you did not (have an opportunity to) further your education?
If so, I hope the day arrives when you make a decision to do so. At 19 you still have talents unexplored, the future is yours to grasp and the world is still open to you. Don't let any anxiousness you may have regarding your capabilites be the barrier that holds you back from what you feel, AND in expressing it. It may not make you personally popular, yet impersonally can mean so very much as a spokes(wo)man for any community you choose to serve.
(Grand) trines signify the inherent talents,(Grand)crosses the 'oomph' necessary to give them the further boost to do something with them. There's also a YOD figure not shown in the chart, between Uranus-Pluto (generation planets) to natal Sun. You possess 'the power to overcome the odds to create change' . That 10th house conjunction, through their ruled houses, could well be the manner to accomplish it.
