Here's a few quick things I feel like I was subconsciously taught about life while playing Pokemon Blue.
Gotta catch 'em all
Meets lots of people! It's not about what you know, it's about who you know. Other people have wisdom, maps, fishing rods, and other items that you'll need in the future. The only way to get those things is to talk to them. Sometimes there will be errands you need to run first but it's just the beginning of what could be a mutually beneficial relationship. Strangers can turn to life long friends and even family.
Explore the world
Have lots of experiences! Maybe you're not trying to be the best like no one ever was but I'm sure you have something that's driving you. Use that motivation to give you the courage to get out of your small town comfort zone and in to the great big world. Those adventures fill your life with stories that you can share with others to encourage and inspire them.
Don't be afraid of what's in the tall grass.
Fear is cage that at some point in our lives we have to break out of. Sometimes our fears are right in front of us and in plain sight and sometimes they lurk in the unknown. Do not be held back because you want certainty and comfort. Take risks and create a beautiful life full faith, hope, and strength.
It's okay to start over
One of my favorite parallels between life and the Pokemon game is that no matter how far in the game of life we've gotten, no matter how many badges we've collected or mistakes we've made, we can start again. It's not as simple as overwriting a save file but we can choose to give ourselves and others a clean slate to become the champion we've always wanted to be.
