Mindset is everything mate, particularly for the more aggressive batsman. Always look to score runs, it is what you're there to do after all!
From personal experience recently - I joined a new club in 2017, got given the no3 spot and I tried to bat like one; be responsible, make sure we don't lose early wickets, get set before taking any big shots on etc. Felt in good nick all year... scored absolutely bugger all.
2018 I managed to get myself opening the batting, first game chipped a longhop up in the air for a duck. Had a good angry walk round the boundary and decided I just needed to focus on each ball and back myself to play my own game, which is looking to hit the ball. The next game I got some loose balls early on and rather than trying to be 'responsible' I just hit them. Got about 20 off my first 8 balls and never looked back - tonned up and ended up averaging 40 for the season.
Don't know how directly applicable you'll find that to yourself but moral of the story? Make your batting about your strengths, if you're an aggressive player then you probably need to be looking to hit the ball. For me personally it's key to play my way rather than think about it - if I get a floaty one on the pads early on and I'm looking to hit it, I'll smack it away for a boundary very consistently. If I'm thinking about being 'responsible' and playing myself in etc then I'll try and nurdle it for one and probably chip it up in the air. Recognise what you're good at and look to play that way, if you're busy worrying about other things you'll make mistakes playing shots that don't suit you. Hope that makes some sense!
