Could use advice on my personal mission and vision statements.?
Good. Perhaps include something about being mentally and physically healthy. “one” and “their” don’t go together. “If one sets one mind” is correct.
Advice? Sure. It's good that you want to learn all about fruit flies - they're important insects that are necessary to the environment/biosphere - but you should specify which genera you wish to learn about, as it's a very general area. For instance, you may be interested in the genus 'Drosophila melanogaster' (the common fruit fly) or genus 'Drosophila suzukii' (Asian fruit fly). And so on. Hope this helped.
