I have been back at work for a couple of days now after the Christmas holiday. The thing I find about returning to work after a holiday, is that any back to work blues are more or less over with by lunchtime. In fact the holiday is usually a distant memory by that time too.
The one thing that I actually look forward to in the morning is getting on my Brompton and cycling off to work. On my commute I can ponder the day ahead. I can catch a glimpse of myself in a shop window and think, Brompton bikes are lovely. I can catch a glimpse of myself in another shop window and admire myself on my Brompton. I can pass the many who are in a car or on a bus often looking miserable.
After a hard day at work the last thing I'd want to do would be to get inside a car and end up in traffic. Worse still would me having to resort to using public transport! Those few minutes before I leave for home are happy ones as I know that I can unwind, ponder a bit more, catch more glimpses of myself in shop windows.
If you don't normally commute by bicycle perhaps give it a go? I am sure you'd find it somewhat therapeutic - even if is wasn't on a Brompton!
