There is so much opportunity in the world

I always think that if something doesn’t work out, there is always another opportunity, whether you see it or not.
Going along with that practice example, after a bad practice, I always have the mindset that the next day’s practice will be better. There is another opportunity for me to thrive tomorrow.
And this is the case with a lot of things I do. If I don’t do well on a test, I have another opportunity to do well on the next one; if I don’t sleep well at night, I’ll have another opportunity the next night; and if I don’t have a good day, there is another opportunity tomorrow.
This is even the case with switching activities. I know that when I stop swimming in 3 more years (when I graduate), there will be even more opportunities for me. Of course I’ll be sad to stop swimming, but I’ll be fine knowing that I can learn to surf or play basketball or learn to cook. There are so many cool, fun things that I can do in the future.
The opportunities in this world are endless so why should I let one of them ruin my day? There is always another opportunity.
