Ok, here's the deal.

First you start with
1/ going to mass (preferable a latin traditional mass). They can be found here and there in Belgium. It contains hundreds of years tradition, old rituals which all have their own meaning. If you can't find any, go to a good normal mass, but without the BS like playing guitar, clapping, woman distributing communion, everyone is saved and all faiths are equal BS.

2/ you go to confession. There are places in Belgium where there are appointed hours at which you can confess. e.g. some days in the week. Look for a monastery,...

3/ pray (some parts) of the rosary

4/ read Holy Scripture ( some sentences are enough for 1 day and think 5 minutes about them )

5/ get good catholic friends and don't fall for the protestant,... BS
