You'll know your creativity when your'e alone...You're probably not performing well because people are around, is'nt that what SP's all about?..I can do ordinary things a hundred times better when I'm alone as opposed to when people are around. Sometimes knowing that I'm a bit anxious is an automatic creative hindrance when all you're thinkin about is people staring at you weirdly or thinking judgemental thoughts about you etc... Dont forget people are mentally built differently I mean like intellectually..personality factors and experiences can also cloud or hinder your creativity but it doesn't mean it's gone it's just dormant and on standby lol...Theres things you know that other kids your age don't know how to do so don't sweat... I got your back dawg in spirit..
