From one who knows, she says how you feel about dating is based on the last date. Same with confidence – except I think you can fake it till you make it with the confidence part – let’s say your last experience (of anything) goes awry – just tell yourself this time it will be different – it forces positive change – because if you have doubt, you will invite a lack of confidence, if you have fear, you invite risk aversion, and if you frown, others frown with you. So kill them with a smile and you’ll see that the next steps get easier.
