Re: Mental Toughness
You must realise though that if you want to be really good you also need to train with people that take you out of your comfort zone. So keep that in mind when you go training. You are doing the right thing by acknowledging your fear, and once you work though the reasons or lack of reasons for that fear you should be ok. Mentally I think we all go through stages like that its over something or other so its pretty normal. It will pass i sure.
Perhaps you should start by setting yourself smaller goals so something like tonight I will train with Mr X next week Mr Y etc...
