I don't think any ONE of these alone are necessarily effective, and some of these ideas are actually bad in some situations...
but if one of them works, please send me my ten grand, lol. Thanks.
don't think so much-------(I think this is a bad idea in some situations)
don't analyze so much
don't think negatively-----------(not too
bad of an idea)
don't put restrictions on yourself
don't blame yourself for everything
don't let other people get under your skin
don't worry about failing
don't be such a perfectionist
smile, laugh, and have a good time
let things happen naturally
calm down and breathe deeply
do it, as Nike says
let go of your worries
be in the moment
say whatever comes to mind
forget the past and focus on the present and future
Just a note
: I agree with StevenGlansberg: there really is no magical solution and things are not so simple.
