I'm still w*rking - so have fewer hours to volunteer - so that makes me selective in what I give my time to.
Since I have sons, ages 10 and 12, I try to focus on things that will benefit them.
- I coach a F.I.R.S.T. Lego Robotics team. During the season that's about 10 hours/week. (and exhausting.) Fortunately, the season is limited - only 4-5 months - and the first month is fewer hours.
- I'm on the board of directors for a non-profit foundation at my sons' public school. The foundation funds enrichment programs the school district can't afford. So I'm involved in fundraising, outreach, herding parents, supporting the teachers... It's about 3-4 hours month except right before the big fundraising dinner... probably 10 hours/week for a few weeks, then.
- I volunteer in the class and chaperone field trips. That's about 2 hours month except when they have long multi-day field trips - then it's 16 hour days for 2-10 days.
When I retire, I plan to continue the above or similar, and will also consider becoming a docent for some local gardens.
