Just find a REAL reason to do it. If that reason is something IMPORTANT for you - u will do it and it wont be that difficult.
Believe or not I was trying to go for that long for more than 12 years. I am still surprised HOW ON EARTH I was able to go for that amount of days!? STILL can't figure it out..:))..... I don't know, may be it is just TIME for that. May be because I am about to start a job as a Head Housekeeper. May be because my boss REALLY counts on me to improve the situation there and I BELIEVE I CAN do it.. I just needed 'clearer' head to start all that. May be I just finally realized IT IS TIME:).
