This dog had figured out that instead of running when he takes a piece of food he shouldn't, that its much better to go up a tree as it gets him time to eat it before anyone can get to him.
You would think that its impossible or that the dog wouldn't even attempt it. A lesson from this is that anything is possible if you try, eliminate words like can't and impossible from your vocabulary. If you have a Dream or a goal don't let anything or anyone discourage you if you believe, it will happen if to try. The only way to know the outcome is to take ACTION, but the truth is in life you will fail, train your mind to think of failures as attempts and keep trying. The great Thomas Edison failed/made 1000 attempts thankfully he did not quit and that why we have light bulbs today.
Keep positive follow your dreams, plan and take ACTION and you will succeed.
