After two failed comics in the past due to lack of planning, I decided that my current one, Badger Badger, would not have the same destiny. The idea is to hold your excitement to release everything early and comprehend that there won't be much difference in starting a series (for example) today or in two months. It is better to have a big buffer and many things planned ahead than having to rush to produce them.
For Badger Badger, I've written the first two chapters in prose (which I do not recommend) and I started converting them into scripts and thumbnails. When I had all the thumbnails for Chapter 1, I started drawing the pages but I've made a slight mistake. When I drew the first two pages for the introduction I got so excited that I decided to share it with everyone, so I created the series, facebook page and some subscribers. BUT I had no other thing done! And thinking I would be able to finish 20+ pages [of buffer] by September, I just set the date of the definitive release fot that month (the Intro was released in August). For my despair, I could only make around 15 pages in 30 days - 1 page being published by week - and I still had to keep drawing during September.
In the end, that wasn't the worst of things that I could do to myself, but it kind of set me in a rush. It'd have been better if I had just drawn all the pages for Chapter 1 (including the introduction) before creating any page and releasing anything.
Anyway, with a buffer in hands (that unfortunately ends this friday), I could spend 2 whole months without having to worry about the pages and focusing 100% on my college activities.
So my tip for you is: calm down, relax, make plans, work with the plans you made and always learn with your mistakes.
Extra tip: try to measure how much time it takes for you to draw an entire episode. For me, it usually takes 7 to 9 hours to draw and finalize an episode/page of Badger Badger, so it'd take around 2 days (dividing the workload) to do it. In case I run out of buffer, I know I can produce at least 1 page per week, considering other activites I have to fulfill.
