You've set out nice goals for yourself. Writers block is an issue experienced occasionally by most writers, you are not alone. Sometimes, taking quality time off from work and writing may help. Other times, writing spontaneously is recommended, just as you did, you never waited for the most convenient time to write, you did it inside a car. That's what being a writer is like! Just gain control of your thoughts and emotions, and you'll definitely do better.
Nice work all the same and I hope you reach your goals.
Just a suggestion, improving on your markdown can be a desirable goal, unless you deliberately choose to centralize everything which to me is not really looking nice. Nonetheless, when someone is able to look beyond appearance, you find gold hidden in unwitting places, and I've found gold here.
