“To live is the rarest thing in the world. Most people exist, that is all.”
– Oscar Wilde
You only have one life, do not waste your energy because it is a precious thing.
I would say that your energy is actually more important than your time. If you are constantly drained of your energy there is no way for you to spend your time doing the things that you want to do.
Take things slowly, do not be in an extreme rush because you have a long way ahead of you still. You do not want to rush into everything and make mistakes or wear yourself out.
Over the course of an entire lifetime there is so much life to live, so much to explore and learn. Although of course, there is no way to live life the “right” way, take advice with a grain of salt.
Live your life the way that you want to live it, just make sure that you can actually live your life.
