"Measure your hand from your fingertips to palm and memorize it. Now you can judge the size of anything without a ruler. I've used this my whole life to estimate distances of all kinds of things. Also pick a finger that is pretty close to 1cm or a joint close to 1 inch and remember which is which. You will never need a ruler to estimate again."
It's actually more like with most tips. It will work well with some people and not at all for others.
The best way is to not stick to one way of trying if it doesn't work.
If you want to achieve something, keep trying new ways until you find something that works even if it seems stupid or irrational.
The most important thing is to never give up.
mmm... ok... bye mum
I live in a place that is hot for most of the year and work a job that doesn't have a dress code, so no pants for me... only cargo shorts. So it doesn't matter when or if I put socks on! HA!
Always.
