The Value of Time
What do you value most in your life? Is it your job, a good meal, or an unforgettable experience? Out of all the things in life, I value time the most. It's something that, once spent, cannot ever be reclaimed.
Think about it carefully. If you have $100, and you spend that $100 on something that you regret, there is always the opportunity to make that $100 again. You might even make $100 million.
On the other hand, if you have 100 minutes of free time to spend, and you spend those 100 minutes on something you regret, there's never going to be a chance to make those 100 minutes back. Sure, you could go to bed 100 minutes later, but no matter what you'll still be taking 100 minutes out of some activity in order to “make up” for lost time, so you're not really gaining those 100 minutes back.
Time is a person's most valuable asset. Spend your time wisely, and be aggressive in saying no to spending time on frivolous activities.
