Set your dream and go for it. If you don’t have a dream then how will you live it? Mine is a sail boat. One day I would love to sail from here to there. Now I don’t know a huge amount about sailing, but I know that I can learn, since I’ve learned most things that has got me here so far. But the most important thing is having the dream in the first place.
Whether or not I will live this dream in particular isn’t really important to me, what is, is the fact that I can dream and so long as I have the power to dream then the chance of sailing somewhere nice is going to happen. What’s yours and where’s yours going to take you?
