Yes. You can.
Step 1) Think it!
If you could do anything, what would you do? Take the first step in creating a new reality — dream big? How do you feel about that dream? Are you passionate about it? How can you fuel that fire? Are you afraid of it? Do you doubt it? Ask yourself how your fears and doubts are protecting you, and use them to your advantage!
Step 2) Speak it!
Take that micro-reality of a dream and make it bigger by giving it more energy. Talk about it with your friends. Get valuable feedback as to how to make your dream come true. Declare your committment to yourself and the world. Watch the passion grow in other people. The more people you inspire the merrier. The merrier for you and the merrier for them. Even if you decide to make a solo journey around the world on a bike, someone has to build the bike, and someone has to build the road.
Step 3) Make it!
Strangely enough, a good idea and a cup of coffee will get you a cup of coffee. We live in a 3-dimensional world that requires honest effort. Even magic takes effort. So, get your community together and get going. They didn't build Rome in a day, but remember you're doing this because you said it would be so, and you thought it would be fun and exciting every step of the way.
Warning: You gotta believe it. Do you have some hidden baggage in your subconscious? D you feel like you're not good enough or you don't deserve it, thoughts like these could be sabotaging all the good intentions and hard work in the world. Dig it up and throw it out.
