Dear Daryl,  

I am going to guess a little, and suppose that your question really is: if I think I have a vocation, what should I do?  

The first thing to do is make a decision.  

No matter what your age, if you think you might have a vocation, take the decision that you are going to follow it, no matter what. That is something you do in prayer, because it is a promise you are going to make to Christ.  

Once you do that, then look at what your circumstances are so as to figure out what the concrete steps are going to be. These concrete steps will depend on circumstances such as your age, present obligations, possibilities, spiritual development, how specific your knowledge as regards the vocation, etc. 

Before entering the seminary you have to get in touch with the vocations director and speak to him about your vocation and your circumstances, and get his advice. Once he gets to know you he will be able to tell you if you show the signs of a vocation, and if it seems like the right time to apply, or if there is something you need to work on before you take a step into the seminary.  

You will have to trust him and work with him.
