Getting over things, is a hard task if you are not flexible, or strong. Now there is mental flexibility and physical, but there is an old odd thing called being stubborn which often has a purgative ring to, being stubborn can also be useful!
What should it be, flexibility, or stubbornness? In many surveys of leading climbers, stubbornness showed, or shined through. Can you get it, or are you flexible enough to slink into a position where you can be more persistent?
Soloing little or big routes was always a great love of mine, I am flexible enough to hang on to this habit as it gives me great joy-joy is where it's all at!
It is not the slow progress that is terrible in training, it's the set backs, or the mental blocks people have that are the big barriers. This year I have had a broken thumb, a broken toe, money problems, and I still just got on with it-in a normal year I would, or might have thrown a wobbler. Where did I get this new found equanimity? I found them in better habits. We are creatures of habit. Try very hard not to be a rabbit!
A good habit is waking up!
A good habit is doing good, or correct things.
A few simple things to get you going, look at a photo of something wonderful, maybe a route, a mountain, or special place, a lovely person.
A good habit is a little yoga.
A few pull-ups.
Failing all that, a good cup of coffee, and get to F….ing work.
