First of all, you must set boundaries on how much time you spend on work, family, personal time and professional involvement Then you need to make a best attempt to meet those goals. If you sleep for the recommended 8 hours per day, that leaves 16 hours per day for all other activities. Travel to and from work (1 hour total), and an average 9 hours at work leaves 6 hours. Say you average one hour a day for yourself, that leaves 5 hours for everything else. Most people spend one day of the weekend doing household duties – groceries, cleaning, laundry, misc. home repairs, lawn care, etc. Sundays are usually spent doing family activities.
Depending upon your stage in your career, pick one professional society that is most currently relative and attend its meetings. Young engineers may find technical groups most rewarding, while more professional associations may be relative for middle age and older engineers. As to support to institutions of higher learning, become a contact for your employer with the college's placement office (you get paid for this time usually). Also, pick one event for the college that you can schedule well in advance that you can do on your own time. My local alumni group does a freshman sendoff each August. Also, there are local college recruitment days that you can bolster by giving an hour or so to.
In todays business environment, it is important to balance all aspects of your life to maintain both your physical and mental health and business and personal relationships.

Thanks for the question Danielle.
Of course, my initial non-reflective response sort of 'danced' around what the opinions of Jessie, Peter, Mitchell, and Richard postulated.
Then I recalled the words of wisdom for such types of decisions about the intersection of engineering-type logic with that of those who have had a lifetime of lessons-learned for such matters.
Rather than paraphrase them, I offer them for consideration below.

So, Danielle, the answer you seek . . .and each person faces…lies within your understanding and life-view purpose you wish to embrace.

Thank you to all who contributed to this thread!
While my original intent was not about setting property boundaries, I did appreciate the multiple insights given as it is important to understand how property lines are determined as well as learn lessons from past projects.
In terms of setting boundaries in the more task assignment side (regardless of it fits under the work, professional society, or friends/family portion), I see a theme throughout the responses that communication is key! Whether it is explaining what is already on your plate to asking clarifying questions (i.e. when does this need to be done or do I need to be the one to do it), you need to have a conversation with the person beyond just "can you do XYZ task?".
I hope to implement this more in 2020!
