If you think that its over, set the goal.
You’re wrong if you think that it’s all over, because you are too old; set the goal.
You’re wrong if you think that it’s all over, because you are from the wrong town, city, county or country of the world; set the goal.
You’re wrong if you think that it’s all over, because you lack the right education; set the goal.
You’re wrong if you think that it’s all over, because you cannot see how to do it; set the goal.
You’re wrong if you think that it’s all over, because you think that you do not have the time; set the goal.
If you think that there is a reason as for why not, then it is an attitude or a belief and not a true and final reason. It is only over when you say it is over. If you say that you can do and will do something, then you will. If you say that you cannot do or will not do something, then you will not do it. You see it is a self fulfilling prophecy. Very often the reason that we give for something as not being possible for us to do, is not actually true. As many have succeeded and done very well despite lacking in the same way as you do, they might even in some cases proclaim it as a reason why they won out.
If you want it, then set the goal and pursue that goal until you reach it.
