If you say it, do it! If you promise, give it! If you schedule it, be there!
Stop talking about it, or making excuses for why it's not happening, or even worse... promising someone it'll get done, yet never getting around to it. "Sorry I was too busy." Enough of this garbage.
Be a person of your word, as this is all you really have after all. The commitments you make to others are the foundation of who you become... make them your bond to society. Make them lessons you will teach your kids and grandkids. Lead by example~ an example that SHOWS (not says) you understand the meaning of respect.
Look in the mirror. Are you a victim of this inaction? If so, put your foot down... draw a line in the sand and say enough! Stop settling for less than you deserve. Are you the person who constantly talks, promises, but never delivers? If yes, then stop. Stop today! Respect their time ~ it IS valuable. Respect yourself, and your personal value to others. Respect the importance of respect, and it's affects on all of us. Without it, what do we have?
If this sounds somewhat hostile, maybe it is. Maybe I've been shown a lot of disrespect lately... maybe I've been demonstrating a lack of respect, it doesn't matter. What truly does matter is that you get upset... upset at those doing it, and upset at yourself if you've allowed it to manifest through your actions.
Errr... I mean the lack thereof.
