Writing daily is great and there is nothing wrong doing it. Using 200wordsaday is a great platform to write at. There is definately no doubt about it. Especially that it is very rewarding to see your streak grows one by one daily.
I have to be honest about this, that there were days that I wanted to skip writing. Just to skip only, because I do not plan to stop on writing as it is a good habit to have.
I usually write at night before I sleep on the bed and there are days that I will be out for varied reason, it could be activities with friends, family's event or even a long tiring adventure day and I could be home late at night. This will make me very tired and sleepy and ofcourse, my mind will tell me just to skip a day.
So if ever I skip a day, my streak will be broken and will then start over from zero. I do not think that it is a bad idea to lose streak from time to time to give way for something else like having an outing passed midnight or even let tiredness rule over because overall I will still write and the number of post will still grow over time, just not as fast as others who do it constantly every day. Well this is not a competition, it is just something to achieve personally.
So if ever there will be a day that I will lose my streak, do not worry, this does not mean that I will stop. I will still write the day after and so on.
