How do you keep up writing for your blog?

Not a special trick: it's easier to write as if the target audience is you instead of other people. I'm motivated to write what I would like to read. Since I like studying quantum computing, i've slowly moved from posting the writings to Wikipedia (https://en.m.wikipedia.org/wiki/User:Vtomole) instead of my blog (https://vtomole.com/).

I knew one colleague used to be very proficient at blogs but the trouble was after a while he would loose interest and start a new one on the new subject, new domain and everything. With time he had several blogs on subjects unrelated but mostly all abandoned. I don't even know what could have been done about this kind of trap, but one thing I learned that starting a blog on a new hobby that you might not enjoy after couple of years is not the way to go.

My blogging is basically me just explaining to myself what I recently learned. People seem to prefer raw note dumps over words and opinions.

I just make small notes for interesting stuff ( usually tech related ) I've done in the past or really want to be doing in the foreseeable future. And I just get on with the best I can.

It's not a blog, but in writing my novel nothing gets me writing down the words like an hour timer and starting after my morning exercise (or 30 minutes).
