Thank you, TheByzantine.
Today I took a big leap and went out to collect pledges for the Heart & Stroke Foundation (it's something we're doing at school) for two hours. Going door to door is definitely something that makes me nervous, so it felt really good to get out there and do it.
I told my father how it affects me when they mention that something is not done, and he promised that he would try to not do it anymore. Thanks for that suggestion, Loveregardless!

I'm going to try to take things more slowly, with smaller steps...that way I won't be easily discouraged and I'll be more likely to get things done.
