Your feeling of negative thinking should be put aside so that you can finally think less and just do the stuff with more confident, after you got the confidence that you needed don't lose faith and keep on thinking positively and forward because, if you let it be like that, you'll lose the feeling of confident and the negative thoughts will come back and makes you become nervous and finally failed.
What i'm trying to say is that, think less and do more because you'll never know what will happen if you do it and don't just predict the consequences that lies some part behind the action
P.S: Don't think short if you're about to do some dumb shyet.
I think that's all
