Yes it is very possible, though very difficult. To show the need and benefits of being a disciple my church did a series a while back on this very topic. I don't think I can get the podcasts of that series anymore though... I will check and edit them in if I can find them.
edit: found it! http://www.lifechurch.tv/message-archive/disciple/1
edit 2: LOLZ! I had forgotten about this series. It has some EXTREMELY funny moments. Tackles things that most other churches stay longs ways away from spelling out. http://www.lifechurch.tv/message-archive/satans-sex-ed Give it a view.
