Just like this tree, you may find walls, fences, and cages around you. These barriers may be built on purpose or on accident, by you or someone else.
Remember, that there is always a way around them, over them, under them, or through them. Establish your goals, be patient, adjust to change, adapt to your surroundings, and don't be afraid of altering your initial direction.
The path to Master Happiness will be riddled with obstacles. Use them as learning experiences, fodder for stories, and unforgettable memories, but never as a reason to stop.
