Make sure to stabilize your dream and get it nice and solid around you before you go on to do other things. Make it as realistic and involving as possible.

For motivation, come up with dream goals. Things that you find interesting and exciting. For ideas, go here. Visualize your goals, imagine them, anticipate them! Watch videos of them on youtube (meaning, if you want to swing like Spiderman, watch some clips of Spidey web slinging).
