Everyone is called to sainthood. Most of us won't be canonized, but we can seek heaven through Jesus. (A saint is someone in heaven.) Sometimes we need more to reach this goal.
Go to confession. If you already go regularly, try to go more often. Each visit to the sacrament is an opportunity for grace.
Try attending daily Mass, at St. Thomas or another parish convenient for your schedule
If you can't make it to Mass during the week, the daily readings are available here. They provide a great overview of the Bible and daily food for the soul.
Find a retreat.
Make a resolution. It's hard to fix everything at once. Pray and identify ONE simple goal and make it your spiritual objective.
Adore the Lord. Adoration is an excellent way to draw closer to Jesus. Visit Him at St. Thomas in this special ways twice a week. If you can't make it, there are 24/7 adoration chapels within driving distance.
