Raise your hand if you've ever said something like this:
"Someday I'd like to take a trip to France"
"I really want to start training for a marathon"
"Eventually I'd like to open my own business"
"One day I'll quit my job and start a band"
Sorry to break it to you, but as long as a goal exists only in your mind you will never do it. If you want to accomplish something, you must take steps, however infinitesimal, toward its realization. There are two reasons for this:
1) Spending actual time will create ego investment in the project. Want to learn to program? Go on Codeacademy and spend a few minutes doing the first couple exercises. After a short time, you'll feel like a budding programmer and the hobby will become a small part of your identity. Want to go to Alaska? Buy a travel guide and make a list of our preferred destinations on the trip. Your mind will naturally connect you to the next steps.
2) Taking action towards a pursuit will tell you that some of your dreams are dumb. When I was younger, I decided that I wanted to compete in a martial arts tournament. The first time I got punched in the face, I decided to cross it off the list. Should I feel bad for "giving up on a dream"? No, because I had no idea what it involved in the first place. This is progress. Since you'll no longer be wondering "what if," you will have more time to devote to the things you really want to do.
Don't avoid big aspirations, but sometimes goal-setting can cloud your mind and prevent measurable action. Accomplishing even the most piecemeal components can help the process snowballs Seriously, close this browser window and take the first minimal step. The fewer things you say you will do "someday," and the more projects you can say you are working towards, the happier you will be.
