Can confirm, as a woman, this is a very good idea. Having brightly colored hair actually communicates a few things at once :
- He’s confident enough to stand out
- He’s at least a little more open-minded than average
- He put some thought into his looks
- He’s not the stuck-up fun-hating “alpha male” type
I cannot stress that last point enough. These days, every girl I know has her radar set to max to get as far as possible from “alpha males”, because they’re just incredibly annoying, self-important pricks. The more you can do to signal you’re not one of them, the better.
4 hours of focused work is generally the maximum, in my opinion. I usually add 4 more hours of low-intensity work on top, to keep up with all the administrative stuff etc.
This is highly dependent on sleeping well and eating healthily, though, and on taking at least one day off per week, if not two.
I’m of the opinion that working hard is foolish, I’m focused on working well. Some days I can do 5 hours, some days I can do 5 minutes. That’s okay, no work is always better than bad work.
