I'll speak about that in another post, friends and family can also be role models too!!! Friends, family, scientists, having a group of friends, competition! I love competition! I always get more motivated when i compete against someone!
I know what you mean when you say some days are better than others... i sometimes don't have any motivation to move my sorry ass, procrastination is soo good! Every time i start to procrastinate too much i hop in the shower and turn the water to cold, it works so well! I get enraged that way!
