K's and pham's contributions are much appreciated; 15-30 minutes a day seems like an underestimate to me.
It depends how you look at it I suppose. Regardless one should not underestimate what can be accomplished with small amounts of effort put forth consistently.
Another place where I put forth small amounts of effort consistently is with my exercise regimen. I do about 40 minutes most days and it will be weight training, elliptical machine, yoga, or road biking. Of those four activities, I detest all of them except for the road biking. And even there my mind wanders. To be able to tolerate these activities I basically have to think about something interesting while I do them. So here's what I do:
1) While on the elliptical machine or between sets of weightlifting, I use my tablet read pretty much every word that is written on the structural engineering general discussion forum. This really doesn't take very long because there's just not that much activity here, much to my chagrin.
2) When I've read everything, I'll spend the remainder of my elliptical and strength training dead time thinking about what I've read and how I might contribute to those discussions. If I'm on my bike or doing yoga, I'll spend 100% of my time thinking about eng-tips threads (can't read on my tablet during those activities). I also tend to take uncommonly long showers which buys me another 15 minutes of thinking about structural engineering problems every day. Ditto for any time spent in my car.
3) When I get to my computer I'm pretty much just pounding out ideas that have been ruminating in my mind for some time. It's high RPM typing, bare bones blue beam sketching, and answering the occasional clarification. It's really only this last step that takes me 15-30 min per day. But, then, all of the rumination time that I've described above is basically free from my perspective. Sure, I could be spending that time thinking about supermodels or my 401K plan but I don't; I think about structural engineering problems. It's just what I do.
