You don’t get to control whether or not any particular college says yes. You can influence it, but the actual decision is out of your hands.
You do get to control:
1) How much effort you put towards preparing for college.
2) How much time you spend worrying about what the answers will be.
The first one is guaranteed to pay off in some way. Even if you don’t get the answer you want from your dream school, taking hard classes, studying, and committing yourself to activities you care about leaves you smarter, better educated, more aware of your talents, and likely to be even more successful at whatever college you attend.
But the second–worrying about which colleges will say yes–does absolutely nothing for you other than raise your blood pressure, make you lose sleep, and ruin what should be an exciting time in your life.
Take control of both. More effort, less worry.
