it happens all the time;)
and I think it's a nice thing!
very often I have an idea that rises me up but the next day I think "Nothing special, no time for it". Then I just understand IT ISN'T MINE, It's nor for me, and I will lose nothing if I forget about it.
it's like a soul voice. If I think about it many times and many days - I really need it.
If I forget about it after sleeping - no need to waste time for it.
