Yes I do that all the time.. lol mostly I spend time and energy on people who aren't worth it tho :P Thing is we cannot know that at the time.. so all we can do is follow our heart and put our best foot forward... give it everything we have.. I think that applies to both things we waste time on and people..
I am fortunate that i have a lot of time to waste :P
I suppose it's a matter of perspective. You know? There was a lot of sand and sunshine, kind of like the beach without the water. There were beaches too tho. Did you know the water in the beach is warm over there? Actually almost hot. I didn't know that.
