They say: Of course I’m serious about achieving my goals! No one says otherwise. Nevertheless, if you are serious, you’ll behave in a manner that proves it. It’s not enough to say it, you’ve got to take steps to move closer to where you want to go, for what you want to achieve.
Too often we talk a good game and do nothing. This lack of effort convinces others you’re not to be taken seriously. They’ll determine your commitment—or lack of—by comparing what you say to what you do.
When your behavior matches your intent, they know you’re committed and you’re serious. If they don’t see it, they know you’re not. As Emerson wrote in Self-Reliance: Do your work, and I shall know you. Do your work, and you shall reinforce yourself.
What’s most important is to prove it to yourself! It motivates you, it spurs you on. The only way to move forward is to take action. Every day, be serious about what you intend. It’s OK to change priorities, just don’t delude yourself about what they are. Always remember, when you’re serious about your goals, you’ll prove it through your actions.
