Well, I don’t have any specific experience with St. Meinrad, I might be able to offer some helpful pointers since this is my fourth year in seminary. I finished my last two years of undergrad in college seminary, and I am currently in Theology II (the toughest year!). Since you didn’t give much background, I made a couple of assumptions, so if some of these points don’t apply to you (for example, if you’ve already called your vocation director), then simply disregard.
Keep praying the Liturgy of the Hours. If you don’t have one yet, find a good spiritual director who can help guide you in this, other spiritual practices, and your discernment. This is key, and you will be asked about it during the application process! If you haven’t contacted the Diocese or order in which you are interested yet, do so as soon as possible. The application process is quite lengthy and will take a long time, and they will also help you in your discernment.
Stay focused in your online courses and do well; you’ll be doing a lot of writing in seminary, so be sure to get the practice in now. But don’t make life all about school and prayer! Be sure to stay involved in your parish, whether choir, lectoring, the Knights, and perhaps most important (in my opinion), altar serving if that’s a possibility. Also stay balanced and cultivate outside activities (for example, I am into archery and amateur astronomy).
Finally, above all else, just keep praying and trust in the Lord. Take definite steps forward, and if you trust in Him, He will guide you and keep you, no matter what the result. I still have three more years, and I can definitely say that each year has been better than the last; it is a beautiful life full of blessings and sacrifice, one that is a true gift!
If you have any questions, feel free to ask them here or drop me a PM and I will try my best. For now, I will add you to my prayer intentions; please pray for me too, especially as I get ready for finals!
