How do you feel when you notice you aren’t doing what you said you wanted to do?
When I notice I'm not doing a thing I said I wanted to do, I pause. I reflect. I re-evaluate my thinking.
Other times, I simply notice: hey, I said I wanted to be doing X and I'm not doing it. I'll stop what I'm doing and get back on -- as if a train is slowly pulling away and I have caught myself chatting, too long, to somebody at the station, who isn't taking the same trip I am. I get back on immediately.
The times I don't get back on track immediately, I say to myself, "hmmm.. I guess that trip wasn't as important as I thought it was." I realize there will be more opportunities or more trains. I'll just catch another.
If I don't have a clear reason for doing a thing, it's easy to get distracted and lose motivation. When the goal is clear and the reason meaningful, it's easier to focus, like a laser, and apply my time and energy to reaching an objective.
Goals are important - especially those with meaning-filled reasons behind them. They are a mechanism that focuses our attention and motivation. When those elements work in harmony, we get achievement. When not, we don't venture ahead and will likely fall behind.
Summary: Goal ahead or fall behind.
