A lot of people work extremely hard towards their dream to fail. Which is fine, but when you start out life being told if you just keep trying and it'll happen then it can quickly destroy the golden years of your career/life. This is often varying per goals too. Just because you love football does not mean you're going to be able to be a pro player just because you spent every hour on it. You're probably better off e joying football, doing enough to get a scholarship, and finding something else to build your life goals around.
If you want to take yourself from where you are to the best chances at your dream, work as hard as you can towards it. But it's also more than fine if you don't want to take that risk, you can often have a perfectly good life without working yourself to death on the promise it'll make your dreams come true if you do.
