Start a diary and write in it every day. I tried to do this several times, but ended up giving up after awhile. One day I'll manage to stop being so lazy and start a diary that I'll actually write in at least once a day.
read the bible.before you look at tracts or other spiritual guides reading Gods word is the most impartant source of our walk with Christ and God. Reading it daily is a good habit to form as we gain more knowledge every time our bible is opened.
