Hey guys! For anyone of you following GTD methodology, how would you arrange the sequence of projects? Suppose you are processing your inbox and you come across something that is a project but would start after the completion of another project. For example, let's say you come across "develop an Android app about X" and you actually have an incomplete project called "Learn App Development", then you would only start the former after you complete the latter. How would you handle this scenario according to the best practices in GTD? Thanks!
