So much is about to happen—wonderful things and hard things; things that will create joyful memories and hurtful things that will bring you to tears. You will learn and grow as a person from all of them.
The most important piece of advice I could give you is to never take a single day, a single moment for granted. Soak up every experience and embrace every feeling, good and bad, that comes your way. The game you love is a vehicle that allows you to go places, meet people and learn things that others might never know or understand. But you have to slow down and take your eyes off the road every so often or you will miss the scenery.
