I would suggest setting yourself personal goals and challenges. To keep you motivated. Personally ive written myself a tick sheet of things id like to do with women ie a pua bucket list I guess. Every night I don't feel like going out or making any effort I look at it and think tonight could be the night I get to tick one of these bad boys off. If I don't go out and make an effort then ill miss out.
I haven't done this but random retarded challenges could kick you into gear also, something like if you've got some mates doing this also you all pick a lame opener for each one of you and you have to use it all night.Things like this could just keep it fresh and fun for you.
