Tip 2: Block out all negativity from your life.
Don't get too stressed thinking about the future. Society can make it seem like you have to have everything figured out by a certain age but in reality, most of us don't know exactly what we're doing. If you're unsure about your future, don't rush into making decisions and don't feel bad about taking more time than others to decide. Life is a huge lesson and don't be afraid to not follow the crowd. If the School->Uni->Job route isn't for you, don't feel like you have to fit in with the rest. You'll figure it out, it just takes time and learning.
Tip 5: Go outside and explore.
Tip 6: Do what makes YOU happy.
