Not knowing where to start

I love arty type things always have....but Im too critical of myself.if something isn't done perfect in my mind,I don't feel Ive acheived anything worth writing home about.I did have big ideas about making jewellry,had visions of what I wanted to do,but as usual it hasn't happened.True I can crochet in a fashion,but again I tend to not see anything wonderful in my efforts.I love art deco things so have started collecting pictures via my pc,which has been my lifeline,as there are alot of art software that lets you have a dabble without any of the mess.Spending time with colours has helped many a time,also getting together music and songs that I download on my mp3...and listen to this when I can't sleep.I expect I am not alone in this perfectionalist type of thinking.Its true that through art,what ever form it takes we can express our feelings more,and often it is relaxing to have done something,even if its not picasso or a Van Gogh.....So this just my little rant about how pathetic my attempts are.Just wish I could construct wonderful things like my sister can,she can sew which I hate,she make the most beautiful cards,which my interest doesn't really lie,not that Id be any good at it.I do look at loads of craft sites online,and get fired up with inspiration,but it all fizzles out when problems come in the middle of my great ideas.I have made movies for my neices baby boy and added music etc,which is the only thing Im slightly pleased with.May start this again,when the muse takes me....Until then I still tread water...trying to make sense of everything and usually falling down rather quick and hard flat on my face......At least talking about it has helped me,guess thats what its all about with this site...would never have thought putting feelings into words would make the slightest difference,but it has.......
