In reply to Daniels735:
I can relate totally . I haven't really concsiously tried hard for far too long . For me it comes down to my frame of mind mostly , I used to really give everything I had occasionally in a gym sparring . When younger I studied & practiced Ju~jitsu & there are techniques known as Mu-shin & Isshin which are basically mind clearing meditive states where you empty your mind completely so you can totally immerse yourself & focus on the job in front of you .
The few times I have done this before climbing it has definitely helped , but I just haven't done it recently . Its worth looking into .
Have also seen a few vids where high level climbers like Alex Huber just go over & over the moves of big routes in their minds until they are burned into the brain , as well as actually climbing them over & over before ( free )soloing them . Does this amount to trying harder as well ?
I think maybe it does . It all leads towards your goal eventually . Would recommend Mick wards Three Grades harder for similar reasons if you've not already seen it .
Also think there is such a thing as trying too hard which can also be a factor , sometimes it pays to know when to call it a day , so you can get back on it with clearer & more focused outlook .
Of course the above could be utter nonsense mind you .
