Everything is a trade off. Watching Netflix or finishing that screenplay. Staying in bed an extra hour or going for that 5 mile run. Spending time on social media or spending quality time with friends and family. In all that we do we are trading one opportunity for another.
Remember, an opportunity is nothing more than a set of circumstances that makes it possible to do something. The key word is possible. Humans have proven themselves capable of accomplishing seemingly impossible feats. If a man/woman can run a 100 mile race in the desert, scale Mount Everest or travel back and forth to the moon, surely you can find a way to accomplish your goals, no matter how impossible they may seem.
Do not settle for less because the opportunity cost seems too high, requires too much and involves unwanted pain. Rather move towards pain and tension as it will make you a stronger individual capable of tackling any obstacle that may stand in your way.
Your time is your currency. But unlike currency you can not make more of it. You have a limited and finite amount of time. Spend it wisely on the right opportunities.
