Don’t rule out a goal due to a superficial assessment of its attainability. Once you commit to a goal, it might take lots of thinking and many revisions to your plan over a considerable time period in order to finalize the design and do the tasks to achieve it. So you need to set goals without yet assessing whether or not you can achieve them.
This requires some faith that you really can achieve virtually anything, even if you don’t know how you will do it at that moment. Initially you have to have faith that this is true, but after following this process and succeeding at achieving your goals, you will gain confidence.
Every time I set goals, I don’t yet have any idea how I am going to achieve them because I haven’t yet gone through the process of thinking through them. But I have learned that I can achieve them if I think creatively and work hard.
I also know that I can “cheat.” Unlike in school, in life you don’t have to come up with all the right answers. You can ask the people around you for help—or even ask them to do the things you don’t do well. There is almost no reason not to succeed if you take the attitude of 1) total flexibility — good answers can come from anyone or anywhere and 2) total accountability — regardless of where the good answers come from, it’s your job to find them.
It’s been my experience that if I commit to bringing creativity, flexibility, and determination to the pursuit of my goals, I will figure out some way to get them. And as I don’t limit my goals to what seems attainable at the moment I set them, the goals I set tend to be higher than they would otherwise be. Since trying to achieve high goals makes me stronger, I become increasingly capable of achieving more. Great expectations create great capabilities, in other words.
