I really like your perspective.
Focusing on what we can do to make this world a better place is much better than making up excuses of why I haven't done enough to make my dream come true.
As you said - it's all in your hands! Do what you love and focus on that.

As for decision making, can't think of a better way to explain my views on this than by words from Alan Watts. His talks inspire me. A lot.

“You do not know where your decisions come from, they pop up like hiccups. People have a great deal of anxiety about making decisions. ‘Did I think this over long enough? Did I take enough data into consideration?’ And if you think it through you find you never could take enough data into consideration, the data for a decision in any given situation is infinite. So what you do is, you go through the motions of thinking out what you will do about this. But worriers are people who think of all the variables beyond their control and what might happen." - Alan Watts
