Finding a good space to learn in this helps. You want flat, smooth ground with a wall or railing next to it. Here are some examples:
A gym or indoor area with a smooth wooden floor and a handrail about elbow height.
A tennis court or outdoor concrete path that is swept free of small stones and has no bumps or cracks. A firm rail or fence is helpful.
A narrow corridor allows you to hang on to both walls. Work your way along and back, trying to hold on less and less each time.
You can start between two chairs placed back to back in front of a wide-open space. Get your balance then launch into space Get two friends to hold you up, or get between a friend and a wall. The friends should be half a pace in front of you and carry none of your weight. Its cheating if you have your arms around their shoulders!
Do not try to learn on grass or rough ground, this is just making things harder for you.
