The way your life turns out is defined by choices. When you’re born, there are infinite possibilities for what you’ll become as an adult. Whether you’re an introvert or extrovert, what career you will have, who you’ll marry etc.. All of that is open for exploration.
Even at this point of your life, whether you’re in your teens or 30s or 60s, there are still infinite possibilities for what you can do for life on earth. And that is what’s so amazing. You can literally do anything you want to do. Make the world a better place. Relax at home with your family. Write a book. Expand your perspective.
Of course there are always restrictions – finances, time – but we need to live life to the fullest when we get the chance. Even in the smallest of ways. Just have fun.
