Here is some advice for guys who may be at the level of calling and visiting religious orders or diocesan discernment programs:
(The Importance of Daily Prayer)

2) Daily personal prayer - Adoration of the Most Blessed Sacrament, the Divine Mercy Chaplet, the Holy Rosary, and the Liturgy of the Hours (If you are busy, try praying at least morning and evening prayer). It is also highly recommended that you try to take 15-20 minutes a day a prayerfully read the Scriptures (Lectio Divina) which is a staple of the Monastic Benedictine Life.
3) Spiritual Direction - (Spiritual direction is a "gathering together" of two in the name of Jesus, the spiritual director and the directee, to help a person to develop a closer relationship with God and to better discern how the Holy Spirit is leading in their life.) For someone discerning the call seriously it is important to meet with your director (either a trusted priest or religious) once a month.
4) The Sacrament of Reconciliation - Again, I recommend monthly taking advantage of the Sacrament.
(Get Involved)
If you are not so already, get involved in your local parish (I'm sure the local priest would love your help). Also, take advantage of groups like the Knights of Columbus who are a wonderful group of Catholic men who practice all sorts of great community
(No Dating)

Finally, the importance of being free from addictions to drugs, alcohol, gambling, sex, and PORNOGRAPHY!!! As you may already know, any addiction, especially pornography will make it extremely hard for you offer the Lord a free and complete "YES" to the divine call. This is not to say that religious orders and diocese are only looking for saints, that's not the case at all. All people, are bound to have the occasional slip-up and sin, yet we rely on the Mercy of God and the Sacrament of Reconciliation which allows us to pick ourselves up, dust ourselves off, and continue on the straight and narrow path which leads to Heaven!!!
