I have 3 but would LOVE to hear more…
You can always have more but you can’t have less
This one’s from my dad and it really stuck with me. You can, and really should, apply this to any intoxicant.
On the pitch is off the streets
This is about getting restless kids, or kids who might be in a bad situation, into sports.
The axe forgets but the tree remembers
Translation on this one: People who cause hurt are less likely to remember than those it affected.


I’ll share (a crude translation of) a piece of song lyrics. It has two great nuggets of wisdom right next to each other!
"There are no meaningless days Or if there are the whole life is So useless that it’s better not To think about it today
And I suppose it won’t be a punishment If we go together for a while When we turn out to be monsters Will the good days be a lie even then?"
The first part, for me, is about the meaning of life. How it must come from within and how it is in every moment. The second part is good relationship advice, in my opinion. Duration does not equal quality or significance. (The monsters part I don’t consider that important, but for some it may be.) And these points work well together. The meaning is in the moments.
The song is Sielunvihollinen by CMX.
You’re cuttin’ a little close to the bone there pal. :'(
