Keeping a schedule will really help, I plan to post Saturday, Sunday and Wednesday/Tuesday. I usually write up the post for the week on the weekend so I can spend more time on it and I have more time to do school work during the week.
Getting blogger block is another issue I have come across so I find that keeping a notebook with me means that whenever a post idea pops into my head I can write it down for the future.
I also find keeping a diary so you can plan out when is best to upload each post. It also means that you know how many you have to post that month, which I have found really useful!
I hope this has helped any of you reading this and if you have any other tips please tell me them in the comments!
