It's always good to set a dream goal and work toward it. Life, of course, isn't simple and sometimes as opportunities or hardships arise, your path will deviate. When that happens, evaluate your path and set new goals. Realistically, you probably won't end up getting to your 15 year old self's dream goal, but that's okay. That's life.

Just keep moving forward and don't get hung up comparing yourself to others or letting your past drag you down. Keep setting realistic goals that you can work toward.
