Whatever comes out of your mouth, own it. Which is why you should choose your words carefully.
Don't think that it is THAT easy to just take back things you've said, promises you've made. It's not. The little thing called Credibility is being eaten away every time you say something you don't really mean or turn back on something you've verbally committed to do.
A promise kept, no matter how small, is another brick in that edifice called Trust. If you've said you were going to do it. Then do it. no ifs and buts. If it's a promise to attend this meeting, attend it. It it's a promise to support someone, then support you must. And if it says 630am or earlier, you should be there 630am, not 635am, not 645am.
If you must, for whatever reason, break that or renege on it, treat that with utmost concern. Treat it as if it was the biggest sin you'll make to that person. Humbly apologize in advance and offer amends. That way, they will see your sincerity.
Hence, never make a habit of breaking promises.
And moving up the chain, therefore, be careful what you do promise or commit to. Weigh it carefully to make sure that you'll be able to fulfill that, no matter what.
Thursdays with CC (TWC): hopefully will be a regular feature. my life lessons.
