Live life each day as if you were climbing to the top of a mountain. occasionally look up to the top of that mountain, it will help you focus and keep your goal in mind, and if for some reason you do not reach your goal move forward reevaluate, and reset your goal because your real problem was you did not have a goal to reach in the first place.
If you do not take the chances given to you in life, then you will be left with regret. Do not make wishes to be better, to have things easier, or fewer problems, wish for more wisdom and educate yourself. Remember that you must take the chances given to you, but you must also make your own chances as well.
