The most important thing is this: do what you know you should do. Most of you who get this far will probably close the post thinking, "That's obvious, I know that already." Whether or not you finish this post is irrevant; it's mostly a reminder to myself anyway. All I know is that it's a fact, so I'm sharing.
In any area of my life where I struggle, it's invariably because I don't follow this rule. Money, health, relationships, whatever! If I'm not doing what I know I should do, things usually don't work out. You know exactly what I'm talking about.
When you feel your weight starting to increase after a string of bad food choices, you know that you need to start eating better foods. But do you? If you're like most people (including me) you don't and then once your weight is totally out of control you're forced to take drastic measures.
Is your business slumping? You and/or your company probably know what you need to turn things around. Are you doing it? Probably not.
Are you in a bad relationship that you know isn't a good situation? You get the point. It's time to act on what you've thought in your head a million times.
If this was easy, we'd all be rich, fit, and happy - but it is by far the most worthwhile thing to work on. If you got this far, look at your actions throughout the day and take note of how you do. If your actions aren't in line with what you know needs to happen, then start adjusting. I'll do the same.
