I have a job that makes me to be too busy and whenever I close from work I feel so tired, and I don't even have the energy to login my forum account. The only time I'm free is on weekends and my family is large, if even you want to do something else you may get distracted.
It actually depends on you OP nobody can in real life application tell you how to manage your time. It's actually up to you to ration everything you wish to engage in to fit your schedule. Of course priority does differ and that should help you infact in setting up a proper Schedule.
Because I know some forum discussion needs critical thinking and if you are distracted it can decline the quality of your discussion.
I don't know about others but for me technical questions I answer and render assistance for isn't something I rush to research first and requires time for me to spill the beans except I'm busy and don't have the time to answer.
