i always worked on several projects at the same time, my problem only was i started in the meantime again new projects and ofcourse the projects which take me years to get finished because i am never satisfied on what i do with them (to much projects to many distractions cant get my time in balance anymore to get them finished at the same time). My new rule from some years ago is......start only one project, focus on that one and start a new one if the other one is finished.....it works much better...for me
