I've been through this in the past, so i can understand you.<p>> Additionally, I'm struggling to establish clear boundaries between my job and side projects. I often find myself working on my side projects during work hours and vice versa, which leads to feelings of guilt on both fronts.
This is one problem i also had, just discipline yourself to make sure you allocate the time properly, for your paying job it will be easy just follow the 8-5 rule, for you personal allocate 1,2 hours for that, no more.<p>For me it was very important to separate the 2 things, make sure that you put something between the 2, physical activity would be good (run, walk, but also clean the house and/or prepare a meal), you will have more energy and passion to put into your personal project.<p>Another big mistake that i made was to think that i could be 99% into work+personal project, dedicating time to other activities such as: playing guitar, drawing, going out with friends (or whatever different interest you have), the important thing is that is something NOT RELATED to standing in front of a PC.<p>After all, we are human being and our soul must be fullfilled with other things as well, job and personal project will benefit more thant you could do by being obsessed with them and not caring about you as a whole.<p>Make sure that a passion doesn't become an obsession.
Hope it helps.
