Tell your friends and family what you are planning. It sounds more real if you speak your plans out loud. It is a bit like convincing yourself.
And most important, you get feedback. You might have thought "No, my plans sound really stupid" but your friends will tell you that your plans are cool. This motivates me on trying new things.
All the people who listened to my ideas can now ask me back - they are my accountability buddies. Without accountability buddies I am nothing.
