I've learned that what seems like a curse in the moment can actually be a blessing, and that what seems like the end of the road is actually just the discovery that we are meant to travel down a different path.
I've learned that no matter how difficult things seem, there is always hope. And I've learned that no matter how powerless we feel or how horrible things seem, we can't give up.
We have to keep going. Even when it's scary, even when all of our strength seems gone, we have to keep picking ourselves back up and moving forward, because whatever we're battling in the moment, it will pass and we will make it through.
I've learned that your 20's are your 'selfish' years. It's a decade to immerse yourself in every single thing possible. Be selfish with your time, and all aspects of you. Tinker with shit, travel, explore, love a lot, love a little and never touch the ground.
